Persistent Application Session

[Zubnix]

Currently when a user exits the compositor, all applications are destroyed. In theory it should be possible to persist all application/client related state to a database. This allows for resuming applications on login after the previous compositor has been destroyed (by ie browser exit). Another use case would be to detach a running application from one compositor and transfer it to another user's compositor in real-time.

Thanks for your great work! I think this one is very critical for Greenfield to become a perfect remote working environment. We don't want to lose our work caused by Internet disruption or browser crash.
