Add a Bungie.net provider

Is your feature request related to a problem? Please describe.
Bungie.net uses OAuth 2.0 and I would like to implement it as a provider so that the API can be used simply for authentication in .NET projects.

@SteveJSzabo Any update on this?

I haven't had any time lately to continue on this. Ultimately my issue is a lack of understanding of how the underlying system works so I can apply the Bungie specifics to it. I am still planning on working on it once life gives me some time to do so, but I certainly wouldn't turn away any help.
