Firefly material

Guys, 

I've re-factored part of the app to angular material so you can see how it's getting.
I will continue the re-factoring.

please, let me know how you fell about the changes.
I will remove that repeated line. Also, I need to fix the agular-material dependency. I'm not using version 0.5.1, but the master branch, which i s on version 0.6 now.
