Toggle for All/Remaining beers implemented
Built randomizer button from BeerListsVC to go to a random beer page. Selects from within allBeers, or if switch isOn, allBeersRemaining
eliminated showOnlyRemainingBeers property & just used the native switch property
created IBAction for switch instead of what I had built
extracted randomizer functionality to it's own method
added missing logic for didSelectItemAtIndexPath to account for showAllOrRemaining beers switch value
implemented use of NSUserDefaults to save showAllOrRemaining beers switch value
defined constant for kBKSUserToggleSetting instead of literal string
replaced NSUserDefault BOOL key with NSNumber value
