Implemented native Gamecube controller support and corresponding emulator hint in ROM header (#408)

Browse Source 
* Implemented native Gamecube controller support and corresponding emulator hint in ROM header

* Added X and Y buttons to VALID_BUTTONS in sm64.h

* Added workaround in controller type detection for mupen bug

* read GC controllers from port 2

* L to Z logic for GC controller uses a threshold

* Changed threshold for L trig to around 33%

Changed threshold based on feedback

* Added gGamecubeControllerPort

* fixed wrong check
