Keyboard Driver Update to v.1.1 (auto mode, bug fix)

Browse Source 
- auto mode: we added auto mode to send F000R command when PS/2 keyboard is not connected. It could be useful to test Terminal (the first major step) and when SmartyKit 1 is assembled but you don't have PS/2 keyboard available
- bug fix: we made uppercase not just small caps lettes but all symbols with ASCII codes greater than 0x60. Now we capitalize only 'a' to 'z' (ASCII codes 0x61–0x7A)
