uac(k): new paramter restore_dlg

- if set to 1, then the module uses dialog variables to store the
  initial and new values for From/To headers
- default set to 0 - otherwise all calls that have changes to From/To
  headers must be tracked by dialog
- result of checking a report from Alex Balashov
