Deleted RESideMenu and associated files, including TAPRootViewController
and TAPSideMenuViewController, in order to make the transition to a tab
bar controller layout.

Once a summoner name is entered in a text field in the start game vc, the
user's info is loaded and a SummonerManager is initialized for that user.
