[ready]Makes bIcon better (#29690)

Goonchat will use the asset cache, you now have to specify who to send the icons too.

Goonchat will now load icons in the background, displaying them once they load. this prevents the message from being delayed while the icons are sent.

Icons that aren't preloaded using the asset cache system will not render on ie8 clients. This is because of a ie8 bug that prevents changes on runtime created images from rendering.
