Non-HTTP URL schemes in redirect_uri

[lawik]

Hi

Have been having good progress with your solution but there is one problem I recently encountered.

As in http://www.slideshare.net/briandavidcampbell/is-that-a-token-in-your-phone-in-your-pocket-or-are-you-just-glad-to-see-me-oauth-20-and-mobile-devices I'd like to use non-HTTP URI schemes and without looking at the code I'd say there is URL-validation going on as I'm getting validation errors when attempting custom schemes.

This could be a hindrance to people attempting to use OAuth2.0 for mobile application auth.

I see this uses the Django URLValidator (https://docs.djangoproject.com/en/dev/ref/validators/#urlvalidator) which defaults to allow http(s), ftp(s) and pre-1.7 it only allows http, in 1.7 it allows specifying the schemes to allow. This still won't work for the custom scheme use-case. An URI is not a URL.

But we can make our own validator, extended from the RegexValidator (just like URLValidator). Pull request coming soon.
