changes for ES 1.0 release

[cleesmith]

This works great with es-ruby 0.4 but it is locked to that version.
What could I change to work with es-ruby 1.0.0 ?

[cleesmith]

Nevermind ... I just forked and changed the gemspec dependency to '~> 1.0' and it works
fine, except all of the results fields are surrounded by double quotes/brackets like:

["some_data"]

Odd, it worked ok before, but I guess all fields are arrays now, so this works:

whatever.results.fields.some_field.first

@cleesmith Yeah, I need to update that dependency to '> 0.4', the fields have indeed changed, but only if you use fields -- http://www.elasticsearch.org/guide/en/elasticsearch/reference/master/search-request-source-filtering.html is now the recommended way.

Thank you! That link was very helpful.
The code, gems, and so on surrounding elasticsearch are well done ... who
knew you could find joy in boring old log apps. A few fixes in Kibana and this
will all be great.

Cool :)
