Fixup saving non-data changes on database lock

* Fix #5107 
* Change setting for non-data changes to Auto save on database lock (or not) instead of marking modified.
* When enabled, database will be auto-saved if there are only non-data changes, but will not prompt the user if saving has failed.
* When disabled, database will not auto-save if there are only non-data changes (same behavior as 2.5 and below) and will not mark the database dirty.
