Backup and Restore homegenie_stats.db

[Jerry]

The update process occasionally fails thus requiring a fresh install and restore. After the restore I noticed that my historical data was lost. I then manually copied homegenie_stats.db from my old install to the new which restored my history.

It appears that this would be useful a part of the configuration backup / restore processes.

Thanks, Jerry

If this data is included, it would probably be good to have a dialog that asks if the statistics should be restored in case one already exists.  Having the statistics backup sounds like a good idea though!
