Using degrees when should use radians

[tom--lee]

In random_rotation, uniform random numbers are generated between zero and 360.

pmx/pmx/atomselection.py

Line 314 in 8176f79

phi = random.uniform(0.,360.)

I copied part of this code for my project and found that phi should actually be in radians, so that the range should be between 0 and 2pi. Unless something is somehow different on my system.
