Bug#503893: Possibly permissions problems

[Johan Walles]

After adding myself to the "video" group I was able to successfully
start Funguloids.

The video group controls access to the following files:
crw-rw---- 1 root  video     195,   0  1 dec 06.09 /dev/nvidia0
crw-rw---- 1 root  video     195, 255  1 dec 06.09 /dev/nvidiactl

The reason I found out was that when I attempted to start Blender, it
complained about not being able to access those files.

If Funguloids needs access to those files, it should say so rather
than just crashing blindly.
