Updated DAO/DTO/model_enum with discussion updates (#30)

Closes #29 

As mentioned in the story, updated the following:
- new FilingState called FILING_INSTITUTION_APPROVED
- change the FilingType enum to be MANUAL (the only one we'll have for
MVP right now)
- add confirmation_id to SubmissionDAO
- add contact_id to FilingDAO

The alembic scripts were already updated to include these updates.
