Feature request, input keys other than arrows

[JaumeAlcazo]

Thanks Marc.

I tried to override the default behaviour of esc key. By default it closes the program but I want it to close my current screen (map) so I've done:

TLN_DefineInputKey(PLAYER1,INPUT_BUTTON5,SDLK_ESCAPE);

and then check for input on BUTTON5 in the main loop. But it doesn't work. I see the default behavior for esc key.
