changes made for sqllite annotation manager

[adam-sutton-1992]

Ignore the spelling mistake on the branch title :).

These are just the quick and fast changes done using sqlite creating two scripts, and one template to handle annotation mulitple documents pulled from ES where the scroll will be take longer than 24 hours.

I don't think any of these changes are nessescary but may be worth looking at or incorporating into the pgqsl fix you've already done:

1. Template for annotations. The major differences are it pulls from ES/OS instead of SQL and after reciving anotations it then adds the document ID to the database of completed annotations before splitting into multiple annotations.
2. annotation_creator.py - Script for creating a new database of completed annotations. If you've already completed mulitple annotations and then get into a situation that the scrolling will reset this script will create a new database and store all documents already annotated.
3. annotation_manager_docs.py Script for adding annotations on a per document basis instead of per annotation. This would ideally be merged gracefully into annotation_manager.py but I did it as a single file in my quick solution.
