Subject: Implement Fitbit and Google Fit disconnect handlers.
X-Git-Url: https://git.octo.it/?p=kraftakt.git;a=commitdiff_plain;h=85a81c5e601b14166dfa0bd9633ba609b1b3ac3d

Implement Fitbit and Google Fit disconnect handlers.

These allow users to actively delete their tokens. This change also
includes:

* Rename the "setup" endpoints to "connect".
* Enforce authentication for the "connect" endpoints, even though they
  don't really require it. It's better to handle authentication before
  redirecting users to the OAuth screen.
