When Settings protections is turned on with password protection, need a way to keep protected controls hidden

[tombogle]

Obviously, we need for the user to be able to press Shift+Ctrl to make it possible to get back into the settings dialog to enter the password, but other controls that are hidden via a call to SetSettingsProtection should remain hidden unless the password is entered. Otherwise, the password can really only be used to protect the settings dialog itself. Probably all that's needed is an additional bool parameter to indicate whether a ToolStripMenuItem should remain hidden if the settings are password protected.
