Subject: Defer char.ini loading and use direct img src for char icons

Instead of eagerly fetching char_icon (with HEAD requests per extension)
and char.ini for every character on join, set img.src directly to
char_icon.png and defer char.ini loading until actually needed (character
selection via handlePV, or first IC message via handleMS). This
eliminates thousands of HTTP requests on join for large character lists.
