The initial import was for 0.7.4, but I wanted to use 0.7.9 for various
reasons, so it's been bumped up.
py-bcrypt: new package

This includes the c portions, and is tested working.
markupsafe: Add markupsafe and c extentions

This is from: https://pypi.python.org/pypi/MarkupSafe which is used by
parts of Flask.  This package helps make sure that the C speedup
extensions are built properly.

I needed to patch around the setuptools/distutils code here.
