Twitter auth via app fails

[futuretap]

In commit 44510ad you removed the OAuth authentication using SFAuthenticationSession. However, in the newest version of the Twitter app, the twitterauth: URL scheme no longer starts the the authentication flow. The Twitter app is launched but nothing else happens.

I found that the old OAuth authentication flow still works fine, so that probably should be the way to go. Requires users to enter their credentials in the web view but at least it still works.
