/**
 * Shows a dialog allowing the user to subscribe to buttons that haven't been subscribed to yet.  This class
 * requires an input list of SDL buttons that have been subscribed to so far.  Button subscriptions should
 * be queried from the SDL service prior to showing this dialog to be sure information is up to date.
 * 
 * The result of this dialog is a list of RPC requests, one request per selected item since SDL can't do
 * these as a batch as of version 2.0.
