output only legistar items to database
adding some scaffolded files and 2 important migrations
seeding legistar data via rake db:seed
Merge remote-tracking branch 'upstream/master'
changed legistar sql to just the insertion statements since rails creates the database
moved legistar sql for consistancy with where we put JSON from legistar rake task
commented script_dir in database.yml so rake db: tasks work w/o Postgres.app

- Hopefully this doesn't then break things for people using Postgres.app.
- tested on a homebrew based system
added debugging printouts and error catching code
adds task to load legistar events from sql file

- should be tested in other environments.
- note that db is hardcoded at the momement. FIXME
refactor district import

Pivotal: 
[Fixes #72926350]
renamed file so generic README documentation is correct

- That is, rake council_districts:load should work now.
