#35 ltris: gamepad: Interpret gp_pause to pause during game.

[Atri]

I noticed that the gamepad key configured for gp_pause is currently ignored during an active game rather than pausing it. The attached patch enables pausing the game when gp_pause is pressed (and released). I have tested this using my own gamepad on Linux (openSUSE Tumbleweed x86_64).

Many thanks (and esp. from my mum) for developing such a beautiful version of tetris.

Thanks for pointing out, I've applied it. :)
