Make Ekos recover its previous state after a KStars crash
It happens sometimes that either KStars or Ekos would encounter an unexpected situation and crash.
In that case, any activity running on a remote or local observatory setup is left hanging, and INDI clients are disconnected. If a watchdog is in use, and there is no other client connected, that driver will make sure the Observatory is safe. But most often any Scheduler/Capture/Guiding session will be lost and will have to be restarted manually.
This feature will make sure Ekos is able to restart its previous activities as quickly as possible. The main point of being able to restart is for a full Scheduler session to continue. The minimal requirement is to restart at the beginning of the job that was executed.
A secondary objective would be to recover Guide and Capture if the Scheduler was not in use. If Capture and/or Guide were running, then the feature should make sure that the state of those modules are restored properly and that imaging can continue.
