Autosave message as draft when session expires

[murray_hair]

When typing a message and the session expires, you will be logged out and you lose your text.
It would be very nice to have a solution for this:
If a sessions expires while your typing a message automatically save the entered fields (to, subject, message etc.) as a draft.

This is a problem inherent to web applications and not RoundCube specific. It's not possible to implement because saving something requires posting back data to server. Before postback, the server doesn't has anything to save, and after session end, a postback is no longer possible.
