@ashfurrow => present terms/privacy consistently

Changed things around so that terms/privacy will always be presented in your modal style by the root view controller. Loading a web view will dismiss the help menu and vice-versa, no matter where you invoked the web view.

Registration button fix to follow. I renamed the extension file since these methods are no longer limited to the Help menu and it's buttons' actions.

Does the WebViewController have any outlets or actions? They'll be broken unless we instantiate from the storyboard.
