Summary of Changes:

- moved es install/start/stop logic into a seperate script
  - `grunt test` now runs the integration tests once for each version of ES we support
  - grunt can now install and run elasticearch (using grunt-run, pure js solution coming later)
  - included seperate es.sh script specifically for starting or stopping elasticsearch
  - url aliases, api, yaml_suite/index.js, and yaml_tests.json, are all now duplicated for 0_90 support
  - the client now accepts an apiVersion argument (undocumented) which defaults to 'master' but can be '0.90'
  - The yaml test runner will now check the name of the ES instance it is connecting to, preventing accidental wiping of ES
