1. Minor cleanup - Cleanup purge/prune handling after merging commands into one.

v1.10.00
|

1. Refactor REPLACE - Processing of DB Replace was awkward.

List of available databases will now be printed in a menu
|

After selecting the desired DB, the candidate will be checked.
|

(Selection may be by list item # or date printed)
|
||||
If valid (DB and Blobs) replacement will proceed normally.
|
||||
|
||||
v1.09.00
|
||||
|
||||
1. Purge command - Add 'purge' command to clean up all temporary transcoder and image files.
