Revert "use HTTP Authorization header for OAuth instead of a URL paramter where possible" (The Skydrive API does not correctly follow the OAuth specification and preflights do not show the authorization header, it is additionally almost impossible to test as only one OAuth redirect URL is allowed and localhost/127.0.0.1 isn't allowed, gotta love Microsoft written APIs...)

This reverts commit 8cc3d661d1e8aaa32cbeaa2512f707f5ad62206e.
