Namespace registered Faraday middleware

Just namespacing the code for a middleware in a module is, sadly, not
enough, as the name when you register it might clash with middleware
from other libraries that register the same type of middleware (for
example, the [Diffbot ruby client][1] registers a `:parse_json`
middleware, which provokes projects using both the twitter and diffbot
gems to raise an error when an error response comes back from twitter.

Add JRuby to the supported ruby version

The travis-ci tests run against both jruby-18 and jruby-19, they are not allowed failures and both are green.
Seems to me, like not adding them was just an oversight. If it isn't I'd like to know the reasoning :-)

Cheers,

FIx documentation typo in favorites.rb

I think these should be `favorite!` not `favorite` because this is documenting the `favorite!` method.
