Create a menu of data cleanup scripts for moderators

Started this off with mod/TARGETS 1.12, ve_search.py 1.1, es_search.py 1.1, cleanup.py 1.1, isfdblib.py 1.14 to give searches for Editor records not in a Series and Variant Editor records that are.

OK, added a few more: Find Missing Editor Records, Interviews of Pseudonyms, Authors with invalid last Names, invalidly spaced author names, reviews that create stray authors, Duplicate Publication Tags, Empty Series, and possible HTML problems in pub notes.
