Removed sign callbacks, rewrite of debug and signing. - Apr'11 // v13 - Menu system for Resolution + Keying implemented, it writing to debug, it sending TVOne commands - Apr'11 // v14 - Fixes for new PCB - Oct'11 // v15 - TBZ PCB, OLED - Mar'12 // v16 - TODO: EDID upload from USB mass storage // v17 - TODO: EDID creation from resolution // !!
