New Onepad GUI based on wxWidget (Main frame almost finish)
Background picture is now embedded
Button binding works
Loading and saving works
Need to add feedback and gamepad, joysticks configuration frame
Modification of the onepad CMakeList.txt
Automatic generation of images headers using perl script
Modification of the test feedback function
+ Isolate every SDL code paths and replace any call to them by call to a generic class "GamePad" of which JoystickInfo is now a child.
+ Now backends can be added by inheriting GamePad generic class.
+ There is just one function change which is redundant with next commits but otherwise commit will not compile(which is more evil).
