Support develop and other things

[ionelmc]

Hey

Almost forgot about this. Your setup.py is much more simpler than what's in pytest-cov but it don't handle develop installs or "easy_install".

This is why I add all those custom commands in pytest-cov's setup.py.

Eg:

.ve/bin/pip install -                                                                                                                                   e .
