Refactor to Open States backend

[grgcombs]

Currently the data comes from my own MySQL server ... Manually collated from Open States, various Texas House and Senate publications, and previously Vote Smart before they monetized their data.

As such, data updates are slow to put together and the users get cranky.

I'm thinking that I should convert the data framework to a newer RestKit, switch to using Open States's primary keys and then use Open States server as the primary provider in the app. Then secondary/auxiliary details will be filled in by my MySQL server.

Open States Data:

• Basic Legislator details
• District office contact details
• Basic Committee details
• All bill tracking (done)
• All district maps
• All events/meetings (done)
• Capitol maps

TexLege Data:

• Legislator partisanship scores
• Legislative email info
• Committee staff and contact info
• Legislative staff and contact info
