Surprisingly enough there where quite some download of this library. On top of that @thambach asked for a GitHub fork.
So I decided to do the right thing: Update things a bit and put it all on GitHub.
The major new thing in this version is a helper library that can be used to load the real library with all its settings. This allows you to only configure all OAuth settings in one place.
Full – updated – details on the library can be found here.
