glsokoban: another sokoban using SDL & openGL libraries

[muggins]

This needs SDL libs as well as openGl libs to work. I used mu's pup here:

http://dotpups.de/dotpups/XServer/DRI/OpenGL.pup

To play type glsoko in a console window, or click on /usr/bin/glsoko.

The keys to use are:

r : restarts game
n: next level
esc: quits game
& arrow keys to move.

Two negatives are that it doesn't remember the previous level you reached, and, probably due to the opengl graphics processing, ball movement in response to keypresses is a bit slow on my 667Mhz 'puter.

The basic game has 108 levels, but you could modify the script to use additional levels in /usr/share/glsokoban/levels.
