*Fixed freeze in theme menu when its empty *Optimized the game list loading on fat/ntfs/ext. This should speed up the loading process. *Added cache of game titles. This will speed up the startup after the cache file is written (in other words on second start of this rev). A TitlesCache.bin will be created in the same path as the wiitdb.xml for this. This should especial speed up the startup of fat/ntfs/ext partitions by a lot if no sub folders with the game titles are used, like GAMEID.wbfs only. That must have been painfully slow before on a lot of games. Should be at about the same speed as with sub folders now. I would still recommend to use sub folders. *Removed wiilight (disc slot) blinking when switching USB port on Hermes cIOSes (thanks rodries) *Added the ehcmodule sources from rodries to the branches *Updated language files
