Fixed various aspects of the gp2x button handling :

- Default button mapping so you can at least click on the buttons
- Keep button press and button release in sync, so you use the same button for the same thing
- Fix display of the buttons

I noticed that ALT is interfering with the buttons names. Maybe we are using too much bits. CTRL and SHIFT work fine.
Also, the gp2x builds start by default in windowed mode at 640x480. This means the screen is hardware scaled down... that makes the program almost unusable, you have to go to the screen menu and switch to a more useable resolution. Finally, all the softscaled modes should be disabled, because the hardware scaler does its work very well :)
