Added Steam Input API support for game controllers

Browse Source 
Added support for getting the real controller info, as well as the function SDL_GetGamepadSteamHandle() to get the Steam Input API handle, from the virtual gamepads provided by Steam.

Also added an event SDL_EVENT_GAMEPAD_STEAM_HANDLE_UPDATED which is triggered when a controller's API handle changes, e.g. the controllers were reassigned slots in the Steam UI.
