#1232 Create cleanup reports to find non-standard External ID values

[Ahasuerus]

Create cleanup reports to find non-standard External ID values. The requirements are as follows:

BN not starting with 294
ASIN not starting with B (allow ignore)
Audible-ASIN not starting with B
Open Library not starting with O
LCCN having anything besides numbers and "-" (allow ignore)
BNB starting with BLL (these are actually BL numbers that need to be moved to the proper place)
OCLC numbers matching the publication's ISBN10/ISBN13

Implemented in:

edit/cleanup_lib.py
edit/cleanup_report.py
nightly/nightly_update.py

Installed in SVN 268 on 2018-12-11. Closing the FR although, based on testing results, we may need to allow the "ignore" functionality in at least one report. We will revisit the issue once all other problems have been resolved.
