Hammered out some changes to make the gem functional

[robsears]

The gem can now be used from within a Jekyll site. Adding the proper options to the _config.yml will allow the searchyou gem to index to a given ES cluster using the _bulk endpoint. Right now the indexing is sort of naive; it basically just indexes the post content to a timestamped index using a type of "post." This can be built out to handle other types, and even accept more settings from the _config.yml. But it's a good, functional starting place :)

from @nz:

• 0 dependencies, just use netHTTP, esp since not using the full client
• in generator, grab as much of doc as we can, no knowledge of ES - backend more modular to support es and solr.

Too many conflicts. Going to close this and submit changes based on the current state :)
