Core changes (Adnan):

-No more uneccesary reconnects to the HUB
-Fragments moved into a sepparate package
-Users can vote only once per song, cooldown to be implemented
-Server to Client packets are buffered and sent in bulks (less bandwidth usages but could get problematic on low end hosts with many clients)

UI & other changes (Dino):
-Vote buttons styled
-Now playing song displayed at the bottom of the screen
-Updated PlaylistAdder, Playlist and MusicPlayer adapters
-Updated layout xml files for the hoster screen
-Changed the global app theme to Theme.Holo.NoActionBar and removed all now-unneccesary code hiding the ActionBar

Current state and next step:
The current objective is to make the app functional for local hosting, which it nearly is (just some fine tuning left here and there to make it more fun to use)

After that (ETA 2 days), we will start making a network of hosts, connecting them all into our web server, which will be a big step forward.
