profilesafe: extended to three modes

Saving configuration is now extended to three
basic modes, from just saving registrymodifiications
to adding user-defined config stuff to saving all
information in the user profile, additionally
configuration information for Extensions is saved.
Added configuration entries for this and tested
saving/restoring.
