[RC] GTK 3 Looking Glass Alternative: Melange

Inspired by rjanjas name "Dune" for the cinnamon-spices installer application, I codenamed this project <a href="http://en.wikipedia.org/wiki/Melange_%28fictional_drug%29">Melange</a>.
Melange is the prescience-enhancing drug from the Dune universe a.k.a. "spice".

The build-in Javascript Looking Glass is quite limited in functionality, and extending it would require a lot of new ui elements, which would mean a lot of work.
So I thought it'd probably be nice to have it a standalone application instead.
This has the advantage that you can use it to some extend with cinnamon broken.

This version uses Python and GTK 3 to create a guake-like looking glass.
It currently has all of the functionality of the original and some additions the original does not have.

This is a Release Candidate:
- All major work is done
- I'm looking for testers telling me if there are any issues left.
- Feature requests can be stated here.

There are a few issues left, which I hope to sort out soon. If you have python + GTK3 experience, feel free to check out the todo list in cinnamon-looking-glass.py.

Currently it runs alongside the javascript version, tho I'd like to replace the javascript version once it is stable.
