@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.
