[Robotics] Feedback on MORSE installation instructions...

[Séverin Lemaignan]

Hello!

Thanks a lot, Herman, for your valuable feedback! (and very happy to 
know that it worked out for you :-) )

The Intel i915 is definitely not powerful enough to run Blender with 
acceptable performances: you really need a graphic card with support for 
shaders.

I've updated the installation documentation with your comments and to 
match the latest version (morse-0.2b1). By the way, you should not need 
anymore to change the PYTHONPATH variable. It's now automatically detected.

See you next week,
Séverin
