Quick delete UI

Quick delete UI

For mass deletion efforts, go to http://hostname/eg/cat/moveto/delete in
a web browser and start scanning barcodes. Each barcode will be deleted
immediately. Note that call numbers and bib records will not be deleted
if the copy was the last one, but the records will no longer show up in
search results for regular patrons... and one could always follow up
with a clean up SQL job to delete call numbers and records where
appropriate.
