Version 1.0.25 -2016-05-08 New GUI Tool: Purge metadata.opf Backup Queue

Does what it says. User discretion is advised.

Useful when all of the books are queued after making a major library change, although the change has nothing to do with a particular book but instead was library-management related. So, no need to refresh the metadata.opf files.

Also, if you do not back up the metadata.opf files since there are so many in a large library and it takes such a long time to create the backup, but rather you back up metadata.db itself, this will flush the queue so needless metadata.opf file activity can be obviated.

See the attached example.

n.b. For my CALM add-on users, the 'Library Tools' Tab has a pushbutton to run calibredb to back up all metadata.opf files en masse for all 'Source Libraries' as fast as possible. Normally, they would be backed up automatically by Calibre at a rate of no faster than ~1 per second, but only when you were currently viewing a particular library. CALM gets the job done much faster, and on your schedule, when you want to do it. And it does it for all 'Source Libraries' at once. CALM has this functionality because it also can update the metadata of all 'Source Libraries' en masse via the various 'Metadata Tools' Tab, such as for standardizing Tags, Genre, Custom Columns, etc. See the attached image.
