[PyMOL] Plugin: Protscale color gradients

[Kristian Rother]

Dear PyMOL users,

One of our students and i have written a plugin that colors proteins by 
the amino acid scales on www.Expasy.ch.

It is available at http://www.rubor.de/bioinf

Also, i have updated the PyMOL tips pages to reflect some topics 
discussed here in recent months.

Yours,

  Kristian Rother
