Merge remote-tracking branch 'cwebber/celerysql'

* cwebber/celerysql:
  Adjust unit tests to match new celery/kombu sqlalchemy setup
  "database" is not the sqlalchemy kombu transport... should be "sqlalchemy"
  Celery and kombu databases should also be .gitignore'd
  kombu-sqlalchemy a requirement in order for kombu sqlalchemy transport to work
  Move mediagoblin dbs out of user_dev for race condition directory-creation reasons.
  Give kombu its own db.  Responding to Elrond "sqlite will lock all the time!" :)
  Apparently an absolute path is three slashes after sqlite:.  Thx elrond.
  Should be all that's needed to switch celery/kombu settings to sqlalchemy
