Refactor checkouts app

Change "checkin" usage to "check_in".

Update URL parameters to the "_id" form.

Add support to checkout and check in multiple documents.

Optimize queries that used an ID list of documents for
filtering using values_list('pk', flat=True). These
queries now use .values('pk') as a subquery.

Add pre save hooks to block new document version uploads.
