Move gamma functions into their own file

[rwst]

gamma, log_gamma, gamma_inc, gamma_inc_lower, beta, psi are enough of the same kind to justify their own file. It eases pressure on the general other.py file and makes finding their documentation easier.

You will need to add deprecations saying the import locations have moved (lazy_import has an argument to do that). Also, you should add absolute_import to the new file's __future__ import(s). (Personally, I don't like the relative imports as it makes it less explicit, but I don't really care, so don't feel like you need to change/revert.)
