Luke: bump version 0.9a
Luke: force 2.1.6 for simplejson (pyon req)
Luke: fixes bugs and range open queries
Luke: Changes to elasticpy, supports 0.19.9

Queries and Filters are now class methods instead of instance methods,
no more chaining. Syntax for the API has been improved, added some new
features found in 0.19.9, still have more work to go though.
