Overlay emote_buttons with emote_selected image from theme instead of generating files (#727)

* Create an "emote_selected" overlay for emote buttons using default theme's emote_selected image
It is used if "_on" button image is not found on the character.
If emote_selected image is missing from the default theme, use a simple transparent black color overlay instead.
Replaces auto-generation of _off images

* clang plz

* use static overlays only
