- HTTP_405 now helpfully includes the verb in the default message
- Remove obsolete `json_asserter` fixture and mixin. Recommend using the `AssertionHelper` directly
- Unregister pytest plugin for `json_asserter`

* Fixes an issue in the assertion helper where 403 responses still needed to have their error defined if vnd=false1, and changes the modified_httpretty_asserter` so that it resets the calls between tests so mocking from one test will not show up in a different unit test.

* Make the parse_value function public so that it can be used in transmission and profiles.

* Add `TransmissionRequest` for authenticating internal requests from Transmission -> Profiles

v.1.0.20
* Fix packaging issue

* Add Exception class for URLShortener
* Refactor get_jwt_from_request to better handle unauthenticated requests
