Improved reliability of gamepad message ordering

Browse source 
The gamepad vs joystick events always happen in this order:
SDL_EVENT_JOYSTICK_ADDED
SDL_EVENT_GAMEPAD_ADDED
SDL_EVENT_GAMEPAD_REMAPPED
SDL_EVENT_GAMEPAD_REMOVED
SDL_EVENT_JOYSTICK_REMOVED

Whenever a mapping is changed, any controller affected by that mapping will generate a gamepad event. You will only get one SDL_EVENT_GAMEPAD_REMAPPED event per controller per batch of mapping changes, where SDL_AddGamepadMappingsFromFile() and SDL_AddGamepadMapping() are each a batch of changes.
