Added diagonals directions keys, fix rom path, ability to load focal/basic games using alias, ColorMode toggle hotkey, other fixes and additions. (#23)

Browse Source 
* Added BK 0010 diagonal directions keys

* Fixed retrieving rom path on windows

* Searching for filename.bin when a game try to load a file without extension (or with its own extension)

* Restore indentation (oops)

* Support for loading focal games using alias "GAME" (type "L G GAME" in focal prompt, then "G" to start)

* Support for loading focal games using alias "GAME" (type "L G GAME" in focal prompt, then "G" to start)

* Fix BK model override

* Alias "GAME" can also be lower case

* Added RUS/LAT keys (binded to insert/pageup)

* focal/basic detection substring is now case insensitive

* Configurable keys

* Restore const declarations where it was not really needed to remove them.

* Fix warnings

* Libretro Options V2

* Change color mode hotkey

* ColorMode hotkey is now configurable

* Removed comment

* Fix Peripheral option

* Change refresh rate from 25 to 50. RA menu now smooth. Need test.

* Restart support

* Fix sending trash keycodes to emulated computer when pressing unbinded keys

* Fix refresh screen after savestate loading

* Better default for color mode change hotkey

* Configurable soft reset key

* Added Hard reset hotkey

* Added ability to left hotkeys unbinded

* Hotkeys now working in callback mode

* Better key mappings default to avoid collision
