Following up on this, I've checked in code that implements auto-restore 
from backup.  It's turned off by default, but it can be turned on from 
the tools menu if you're running Chandler from SVN.

As an added safety measure, I have auto-restore first make a binary 
backup of the repository before loading backup.chex.  The binary backup 
is roughly 5% of the size of your repository, so I don't think you'll 
notice the space.

We should discuss whether we want this turned on by default.  I 
definitely notice that there are a few preferences that we aren't 
backing up to chex which get reset every reload, which is a minor 
annoyance.  Other than that, auto-restore seems to work great.  I think 
it's a little slower than purge, but the startup dialog gives you 
feedback during the process, so it may be psychologically less frustrating.

Sincerely,
Jeffrey
