  • Revision ID: teddy@recompile.se-20150802164529-pemtk1agiqluoiua
Deprecate some D-Bus methods in favor of D-Bus properties.

The following D-Bus methods on the interface
"se.recompile.Mandos.Client" are redundant, and are therefore
deprecated:  "Disable", "Enable", "StartChecker", and "StopChecker".
Instead, the D-Bus properties "Enabled" and "CheckerRunning" should be
set, as was always also possible.

* DBUS-API (se.recompile.Mandos.Client.Disable): Remove; deprecated.
  (se.recompile.Mandos.Client.Enable): - '' -
  (se.recompile.Mandos.Client.StartChecker): - '' -
  (se.recompile.Mandos.Client.StopChecker): - '' -
* mandos (ClientDBus.Enable): Annotate as deprecated.
  (ClientDBus.StartChecker): - '' -
  (ClientDBus.Disable): - '' -
  (ClientDBus.StopChecker): - '' -
* mandos-monitor (MandosClientWidget.keypress): Set properties instead
                                                of calling deprecated
                                                methods.
