Too many bugs in 0.64.7, so here is a quick fix for :
- no more stdout.txt file generated when launching the program
- the shaders don't turn the opengl interface to black anymore
- controls using the command.dat graphics can be changed again (0.64.7 was just exiting in this case).
Also the command.dat graphics are a little better, and I managed to add 1 last shader, not totally sure it renders correctly though...
And added a few combination controls to cps1 and cps2 (not a lot).
Thanks to the testers who quickly spotted the problems !
