Implemented delete-all-but-n and delete-older-than.
Implemented compacting.
Added the --dry-run option, which currently works for deleting and compacting, but not restore or backup.
Added output to console for use with dry-run, and added option to redirect this to the log for use in service mode.
Still needs a work over in terms of error handling, progress reporting, warning output, refactoring etc.
Also misses the volume reuse/reclaim algorithms.
But it passes the unit tests now, with and without a local database.
