Use requests rather than urllib3 (#103)

* Replace urllib3 w/ requests.

* Pass through cert verify, timeout opts. Put verify_cert back to True by default.

* fixing tests.

* fix tests

* Fix older requests str problem

* Fix more encodings

* Post as formencoded with pre-JSON'd data. Test fixes. More tests

* Fix tests w/ form-encoded bodies.

* order

* optimize nearitude

* Use context mgr form of Responses. It's nicer.
