-Wii System Menu now recognizes DVDs using the Load Disc/Eject feature!

Games hang though (probably due to unknown ES call)
-/dev/di IPC: Cleaned up code and fixed a bug (which I used to accidentally find out what I did), added Volume eject feature for VolumeHandler. 
-Partially documented Wii DVD cover flags.
-Files opened in Wii Read-Write mode are now set to append.
-Removed annoying overhead-ish "Idle" log message.

As for /dev/di: Someone clearly didn't know what he was doing in that file. Someone freed memory which didn't belong to that file and then complained about a crash. Needless to say the problem is now solved.

Big TODO on the /dev/di code though, ExecuteCommand is practically doing nothing but reading.
