Remove unnecessary file existence check in GMenu2X -> InputManager

Browse Source 
Instead of checking which input configuration file exists among 2
choices, then asking InputManager to load that file, InputManager
itself now performs the resolution based on whether ifstream::is_open
returns true for each choice.
