Develop

I changed the code to use the pkg_resources module, to load stuff in a safer way, thus allowing installation in home directory / even using eggs.
There are still some minor issues to be fixed, but now the application is running.

I had to create a script to autogenerate dbus ``*.service`` files to be installed in ``~/.local``, as of course dbus isn't aware of all the virtualenvs thing.

Everything seems to be working fine, although I'm having some dbus/sqlalchemy-related issues that prevents tests from succeeding (I'm going to debug them, but they're not related to the new code I introduced..).
