Added a .mailmap that maps addresses in bzr to people's real, preferred

e-mail addresses. (I made a few guesses along the way, feel free to
adjust according to what is actually the preferred e-mail)

Added a couple of methods to nova.utils to parse said .mailmap and do
the appropriate (though highly naïve) replacement.

Apply mailmap replacement in changelog generation in setup.py.

Add a unit test that checks everyone is properly listed in Authors.

Add sleepsonthefloor to Authors. If anyone knows the real name, please
add it.
