SFX and blip players largely remain the same.

For the music player, we now have to implement network streaming
natively, we no longer have a convenient function that did everything
for us. I introduced QNetworkRequest to download the stream in memory
and signal when it's ready to be decoded and played back. The size is
guarded to prevent the client from accidentally downloading terabytes of
audio.

Delete QFutureWatcher, we no longer need it for concurrency. miniaudio
uses a separate audio thread. Network donwloads and communication with
the track name display are handled by Qt signals.

Also, delete an odd "music.txt" feature. Its purpose was specifying
offsets for loops in a text file per track, but it remained obscure and
unused in practice.

Unsupported:

- Large streams, including unbounded ones (radio). We'll need a ring
  buffer for that, and a mechanism to write to it from the network and
  feed it to the audio thread.

- Effect flags: fade in, fade out, sync pos. Ignored.

- Audio device selection.

* Simplified ChatLogPiece

* Suppress application volume when alt-tabbed
Add a "suppress_audio" slider setting, 50% by default, which decides how much audio remains when the client is not in focus
Add a "muted" setting for blip, music, and sfx players
Add update_audio_volume func

* change "suppress" to "how much audio is suppressed" instead of "how much audio remains"

* Fix last commit just flipping the behavior and being ultra wacky

* Fix evidence present sound ignoring audio suppression settings

fixes #561

* Remove get_static_image_suffix (webp, gif etc. can be non-animated)
Replace QList<QString> with QStringList

* forgot to remove static image from aoimage

* Simplify get_theme_path, get_custom_theme_path and get_default_theme_path all into a single get_theme_path func
Add a default_theme variable which defines the currently recognized default theme
Add a new "get_asset_path" that will be used to simplify asset resolution considerably

* Simplify AOImage set_image function to use get_asset_path
Begin working on the subtheme system

* Add p_default_theme for get_asset_path
Implement get_asset_path for AOButton

* Condense aolayer path lookups into the get_asset_path function

* Get rid of get_font_name due to underuse (and it just does the same thing as get_design_element anyway)
Get rid of get_char_shouts (use chat= instead)
Use get_subtheme() instead of subtheme (because get_subtheme() can perform overrides based on the user's settings)
Make get_color() use get_asset_path()
Make get_design_element() use get_asset_path()

* Adapt a whole bunch of text_file_functions to the get_asset_path method, fixing an enormous amount of invalid path resolutions
Unfortunately I have to keep backwards compatibility for the backwards ass config.ini method for the chat markup (new way is chat_config.ini)
Get rid of get_theme_effects and implement the stacking behavior into get_effects instead

* Program doesn't run, color lists stop generating for some reason
Also implement safety checks for the asset path generator

* Fix a really tricky issue that popped up regarding char_color_rgb_list not being generated, causing segfaults

* Address the sfx player path resolution being really, really stupid and resolve major inconsistencies (such as the bug where objection sfx wouldn't be playing despite the default theme or default misc folder having them)

* Fix sfx path resolution being funky (apparently D:/Qt/Projects/AO2-Client/bin/base/themes/default//objection.wav is a valid qt5 path...)

* Implement:
get_asset_paths - Return an untested list of universal paths from the provided args
get_asset_path - Loop through the list of provided asset paths and return the first valid file
get_image_path - Loop through the list of provided asset paths, apply get_image_suffix and return the first valid image file
get_sfx_path - Loop through the list of provided asset paths, apply get_sfx_suffix and return the first valid sound file
get_asset - return an asset (must contain file extension) from the get_asset_path() applied on the get_asset_paths()
get_image - return an image with get_image_suffix() applied on the get_image_path() for the get_asset_paths()
get_sfx - return a sfx from provided args with the uniquely constructed asset path list for sounds

Rename old get_sfx to get_court_sfx for better clarity of its function
This replaces previous asset stuff I implemented, as I think this is a better solution lol

* Add a new get_config_value that obtains a value from the config that matches identifier
Adjust all calls to get_asset() to actually look for a config identifier value instead, so even if a config.ini is found if it doesn't contain the identifier we want we keep looking

* Fix effects.ini sounds not working
Remove debug text

* Make it so even if you miss the required asset, and don't have a missingno, the viewport still doesn't freeze up due to waiting on Objections etc. due to signals.

* Implement default_theme option for courtroom_design.ini, allowing you to make themes that inherit from other themes that are not default.

* move sounds folder lower in sfx pathlist

* fix realization sfx not being fetched from config

* Make aosfxplayer actually use get_sfx I made
Move sounds folder path check last in get_sfx

* I thought this would fix QSettings::value: Empty key passed but I guess not, that annoying error will keep pestering us :(((

* Remove silly .png exception for SplashLayer
Fix static image Objections freezing the viewport due to done(); signal that never arrives

* Make WTCE cooler by including a stop method for witness testimony indicator, and add support for custom WTCE

* Reduce code duplication for get_sfx

* Fix the program hanging/entering an infinite loop/segfaults/a number of nasty issues due to done(); signal being sent as soon as playback begins if the image is invalid.
This is done by removing the file_exists check, and letting the rest of the functionality handle this case - the system is robust enough and treats an invalid image as a static image.

* Fix segfaults with AOLayers by sanity checking using max_frames
Fix "Pixmap is null" console spam

* You'll hate me for this.
Make it possible to have fully animated AOButton and AOImage

* Add a settings option to toggle animated themes on or off

* Add a setting for animated theme elements
Add a "static image" toggle for get_image_suffix

* Fix custom chat and generally the chat boxes not having consistent behaivor with subthemes
Add a settings option for subthemes
Have AOImage keep track of its last valid path

* Add SubTheme (ST) packet. Pass subtheme as arg0, and "1" if you want the client's theme to be reloaded.
ST packet sets ao_app->subtheme no matter what. It will not reload theme unless the user has their subtheme set to "server".
Fix showname widths by rearranging font metrics to do its calculations *after* the showname font is set, and not before (making it lag behind the correct display size by 1 msg)

I'm somewhat confused as to why this wasn't enabled to begin with, since all the necessary code is here.

Closes #306, and fixes the issue with realizations being cut off by other sounds.
