Code cleanup / Quality of Life updates

Adapter::get, post, put, patch and delete all had non-optional parameters for $headers and $query or $body. These have been made optional. I also re-ordered the parameters as $headers was never used while $query/$body were heavily used. I also condensed and removed some duplicate calls so that every call to Adapter::get/post sends that call to Adapter::request. It could use a magic method to do this but it might make it more difficult to test.
