Updates for show "repair" processing

InternetArchive/future_upload: Added logging and debugging

InternetArchive/ia_db.sql: Added new tables

InternetArchive/recover_transcripts: New script to run on 'borg' and
    copy missing files from the backup disk to the IA

InternetArchive/repair_assets: More comments, including one about a bug in the design.

InternetArchive/repair_item: Fix relating to octal numbers (if there are
    leading zeroes in a number). '_DEBUG' is now in the function
    library. Added comments to explain obscure stuff.

InternetArchive/snapshot_metadata: New Bash script (to run on my
    desktop) which collects metadata for a show and stores in in the
    '~/HPR/IA/assets' directory. Runs 'view_derivatives' on it to find
    derivative files for deletion.

InternetArchive/tidy_uploaded: Moves files and directories containing
    uploaded files into a holding area for later backup. Added
    debugging, logging and a 'force' mode.

InternetArchive/upload_manager: Manages 'ia.db' (on my workstation).
    Needs many updates which have just started to be added.

InternetArchive/weekly_upload: Old script, now obsolete.
