[gentoo-catalyst] [Patch v2 2/4] Catalyst: use a more pythonic method to import modules

[Dylan Baker <baker.dylan.c@gmail.com>]

Rather than appending a directory to the system path, this patch adds a
__init__.py file to modules, which allows python to search it, and it's
children for python modules. This also requires changes to a few of the
module files to make them happy.
