Bug 475727

SUMMARY
At the end of an observation session, it is necessary to park the mount and retract the focuser to achieve a stable and known position for it. 
These actions may be necessary to facilitate equipment storage. 
Forgetting to command the retraction of the focuser at the end of the session makes setup and adjustment during the next session more cumbersome. 
The purpose of the modification would be to command a specific position of the focuser upon parking the mount. 
An alternative would be to have a session closure button that would command both the parking of the mount and the retraction of the focuser, and possibly other closing actions.


STEPS TO REPRODUCE
1. End a session with focusseur out.
2. Powerdown
3. Manualy Retract the focusseur
4. Start a new session


OBSERVED RESULT
- Focusseur need to be resync.
- Focusser presets are "far" from focussed position.

EXPECTED RESULT
- After closing the previous session the focusser will not move durring packing.
- On openig a new session :
   Focusser preset is directly in focuss position (Save the temperature, and machanical errors)
