[PyMOL] Slightly updated and moved tutorial

[<chu...@in...>]

Hello,

I have moved the old PyMOL tutorial to the Dr. Eltis lab server. The new
link is:

http://137.82.122.63:1000/pymol/index.html

This should eliminate the pop-up ads!

If you would like me to send you an updated version of this tutorial,
please let me know and I can send you the .zip
