FS_AddPack()

qbool FS_AddPack	(	const char *	pakfile,
		qbool *	already_loaded,
		qbool	keep_plain_dirs,
		qbool	dlcache )

Adds the given pack to the search path and searches for it in the game path. The pack type is autodetected by the file extension.

Returns true if the file was successfully added to the search path or if it was already included.

If keep_plain_dirs is set, the pack will be added AFTER the first sequence of plain directories.
