Redirect url for mobile app

[camanjj]

How would it be possible to add the ability to use a custom url scheme for the redirect_url for a mobile app. For example: mycoolapp://callback

Hmm, the only change that needs to be made is in authorization.py – switching away from a validator that enforces https:// to one that disallows http:// but allows {'https://', 'any-custom-scheme://'}. Mind submitting the PR with tests? Would be happy to accept.
