Load equipped hud textures

[SinZ163]

rather than panorama/images/hud/default/actionpanel/portrait_wide_png.vtex_c it would be either panorama/images/hud/**HUD_SKIN**/actionpanel/portrait_wide_png.vtex_c or even simply resource/flash3/images/hud_skins/**HUD_SKIN**/actionpanel/portrait_wide.png

Current way to hacky do it is listening to the inventory_update event, and have a hardcoded database of items_game.txt to get the correct pathings to the images.

• Wait for valve to let us do this correctly
• Get this working as a proof of concept
• For the time being, get the rest of item_games.txt hardcoded
• Get the rest of the images into the correct folder, with a panorama file to compile them all Switch everything to raw:// so we don't need to.
