that animated icons can be done with it. - Changed FImageCollection to use a TArray to hold its data. - Fixed: SetChanHeadSettings did an assignment instead of comparing the channel ID witg CHAN_CEILING. - Changed sound sequence names for animated doors to FNames. - Automatically fixed: DCeiling didn't properly serialize its texture id. - Replaced integers as texture ID representation with a specific new type to track down all potentially incorrect uses and remaining WORDs used for texture IDs so that more than 32767 or 65535 textures can be defined.
