Initially, to fix developer login flow I edited the client to support the different authentication flow offered by vanilla bananas-api, in short, when using github, the flow is:

> GET /user/authorize
< 302 https://github....etc
Client shows redirect url in commandline for copy-pasting.

While using developer flow, it is:

> GET /user/authorize
< 200 OK <login form>

My initial fix in bananas-frontend-cli detected a 200 response with html content and then showed the URL that was originally requested in the CLI for copy-pasting.

This PR changes the developer flow on the bananas-api side to:

> GET /user/authorize
< 302 <request-host>/user/developer?code=xxxx
Client shows redirect url in commandline for copy-pasting.

The original logon form is now hosted on the /user/developer url.

This allows an almost unmodified client to connect to the API. Unfortunately, in the client, the audience is hardcoded so some changes will still be required. Expect a new client PR to arrive soon :)
