committing Ettore Pasquini 6DOF patch for linux

As previously the plugin itself is available
on his site : 
http://cubelogic.org/blender/3dcnxplug-lin.c
or on mine (soon) :
http://jlp.nerim.net/dev/6dof/

Please let me know if any problem, i cannot
test.

We have now patches for our 3 main platforms
features are still minimal, but will follow
soon.
