[Lazarus] Auto session store etc.

[Florian Klämpfl]

Is there any possibility that lazarus auto stores the current session 
(project file, source files, session information etc.) every xxxx s?

Background is that I am starting another trial to use linux as desktop 
system but within in a few days I have already lost changes because 
lazarus was just killed on shutdown (well, actually I would prefer to 
have linux just hibernating instead of shutdown, but this is another story).

Furthermore, is there any option to store the green bars which indicate 
changed sources between different runs of lazarus?
