Adds booting from drive to gui. disabled as it is currently too slow unless it is a virtual drive Changes DriveUtil to start checking at D: as it is unlikely that a, b, or c will be a cd/dvd drive Addes DriveBlob functions, untested on linux/osx probably needs more work Removes duplicate message from EXI_DeviceMemoryCard.cpp when creating a brand new memcard git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@2345 8ced0084-cf51-0410-be5f-012b33b47a6e
