Adds a basic user preferences controller

Not fully implemented. Somewhat abstracts user controllers.
Gets username from ConfigManager

Removes changes to LoginController
Adds common functionality for getting users to a single file

MockNetwork complains when testing, going to see if that happened in
feature-useremail
EmailController extends AbsUserController

Extension of last commit; this file wasn't included for some reason.
EmailController extends AbsUserController

Now it actually extends it instead of a nonexistent interface!
Adds basic GUI elements to the view

UserPrefsController is now a singleton because there will only be one
user on at a time.

Known bug: preferences tab doesn't close
Known bug: doesn't grab the user before first opening the preferences
panel
Fixes bugs in previous commit.
Adds database storage of user prefs

May or may not work, needs a look over by someone else
