Allow StGIT to be installed in a local directory

StGIT should no longer rely on being installed under /usr. This has
implications in the default python search path, the /etc/stgitrc file
and the /usr/share/stgit/templates directory.

By default, the 'python setup.py install' command will now install StGIT
in the home directory of the current user.
