Fresh export from database with columns switched; basic edit performed and initial files created

Needed to switch metadataDescription with metadataTitle for ease of
creating ShortTitle. Re-created all initial files (pure output, basic
edit, working copy, and first batch [events1]) from new export. No
edits performed on events1.
Added to "basic" edit so starting point is closer to final version

File “afterBasicEdit” now includes tabs being changed to ^^, creation
of mediaLocation field, and removal of empty image fields.
