setup foreign keys for source/header info

[KaylaCrush]

right now, I'm saving the source_name, date_range (should be source_date_range, REALLY), and source_type on every row of every table. This is because the combo of source name and date range is the one unique thing about every disclosure page, and I want that relationship to be maintained.

But that's a bad way to do it. What I SHOULD do is add a source_id column to the headers table and each of the subsequent tables. That way I could remove souce_name, date_range, and source_type from all of the baby tables and just have the one numeric column that links back to the header.

• [x] after saving the header, get source_id and apply it to each table
• [x] remove the triplicate source info from every table (really just, stop adding it lol)

done, still some bugs to work out with table inserting though
