Controller Configuration UI and JSON Config (#760)

* Initial controller hud ui

* Reverted fbdemo changes

* Moved config to json and implemented controller config

* fix build on linux, gitignore new config file

* fix build

* Fix compilation and file directory paths

* Call save on cvar save

* Fixed cvar loading and added deck slots to the config

* Changed control deck port 0 to use a physical device by default

* Added gyro and rumble & fixed loading errors

* Save config on toggle menubar

* fix linux build

* Fixed drift calculation

* Controller config now saves when pressing F1

* Removed ExitGame hook from ImGuiImpl

* Moved mappings to a map

* Added GetKeyName

* untranslate scancodes

* Fixed hud layout on keyboard device

* Fixed keyboard read on hud

* Fixed crash when reloading controllers

* Removed ConfigFile and changed file extension

* Changed Dummy to Disconnected and fixed filters

* Removed function leftover

* Changed ControllerHud to InputEditor
