Added Rocket Pants and sample data_sources api controller
Got the API wired up.  Currently no authentication or authorization. :-(
Holy crap, it works!  Need to write tests now.
Fixed deprication warning
Removed index creation because of later migration error.  Table actually deleted in a later migration.
Removed spec test for blobs.  Will create cucumber tests.
Updated blob index to remove the display of the checksum column as the "id" will show that.  Removed the actions.
Minor reformatting
Removed remnats of old serializaton api trial.
Reformatted Gemfile, updated database_cleaner to non RC version, added cleaner support for cucumber.
Added Blob model tests.  Added the json_spec helper (json_spec.env.rb) but still can't get it to work in cucumber.
 Fixed up the blobs create to remove the :id and add and index to checksum.  Also updated the seeds loader.
