Cleaned up GUI.

	-Added gui skins to give consistant look/feel
	-Added more functionality to the renamed Network/NetworkManager script
	-Added a dummy login screen with a password athentication trigger
	-Added basic User states, eg Authenticated, ConnectedToMaster...

I also removed some dumb scripts and the loadingScreen scene, which I realize now was also dumb. Just fof fun I added a dumb mouse cursor and a new dumb icon. If you have pinned the testbuild to your taskbar, build and repin to see how awesome it is. 

Please review for any obvious bad ideas and to familiarize yourself with it. Don't forget ctrl + ".cs " is amazing.
