Adds has_oral_argument scrapers field and renames has_scraper field
to be more specific. Tests pass, OK to deploy.
Changes the model to only add the fields. We will do a schema
migration with this, then a data migration, then another
schemamigration to remove the fields that are obsolete.
Should do the data migration for the search app and the initial
migration for audio.
First pass at moving the court object from Document to Docket.
Makes all tests pass and adds (passing) tests for bulk files.
Good god this has a lot of changes:
1. Changes cases_cited to opinions_cited and attempts to replace
throughout the code base 'case' with 'opinion' where the latter is more
correct.
2. Adds a pre_save signal to citations that updates the docket
whenever a citation is updated, including tests for this new code.
3. Adds tests for the dump lib and some other areas.
4. Updates the URL structure to a new format!
5. Adds a new page (that's hidden by default) where you can see all
the items in a Docket.
6. Speaking of which...adds the Docket object in its final form and a
 data migration tool to populate it.

Big changes.
Bunch of changes to API and other areas.
Merges changes accidentally made in the default branch.
The great simplification of the callers has begun and a working
opinion scraper and backscraper are both complete. Now it's on to the
 audio one, which will be painful.
Minor touchpoint before switching branches to grab something from
default that's not here yet.
Massive commit that lands first version of functioning audio scraper.
Absolute monster of a checkin. Scraping and indexing of oral arguments is now supported. Next step is making search work.
Checking in to switch branches safely.
A number of big improvements to make search work.

1. Solr core installation now works and has working instructs in the docs.
2. Search for oral arguments works with all fields coming back appropriately, though with a few bugs.
3. cl_update_index is renamed and should now be generic for various types of objects (need to verify).
Search is now debugged on the front end with the exception of the jurisdiction picker.

Also, I've bumped the sliders up to 20000 citations.
Adds podcasts and refactors the current set of feeds.

1. Integration points: A new item to the footer that shows feeds, a new RSS icon on all search results pages.
2. New podcasts created for every jurisdiction, and for oa search results.
3. Removes the feeds app, and refactors the code from there into several feeds.py files, which are crammed into various apps.
4. Fixes issue with inaccurate audio length estimations by switching to a constant bitrate. This allows us to put the duration in search results, and I've done that as well.
Add search thing to homepage for Google
Fix links to google groups
Minor tweaks to podcasts after a final read through Apple's docs.
Updates sitemaps for audio. Refactors urls.py into many files. Moves casepage to opinion_page.
