Summary: The change basically just sets the session delegate in the constructor so
it's available when handleOpenUrl is called.

Test Plan: Ran the DemoApp and ensured SSO still works.

Remove auth.expireSession call from SDK

Summary: The expireSession call was put in as a precaution to make sure that
apps sessions were really no longer good. However, this is unnecessary and it
causes issues with apps that were expecting the session to remain usable even
after the user logged out. So let's remove this call and leave it up to the app
developer to expire the session if they want.

Test Plan: Logged in and out of the demo app.

Unless the server indicates a "service_disabled_use_browser" error, fallback to the inline authentication dialog in -[Facebook handleOpenURL:]
Merge pull request #382 from FunkeeMonk/inline_fallback

Fallback to inline authentication dialog if SSO login fails.
This reverts commit 74ae9527cb82663911973fc6286e142928af92ce.

The original behavior is the correct behavior as it prevents random errors from popping up the inline login dialog.

Update sample app to show how to handle dialog request results

Summary:
Part of the discussion of the abandoned diff https://phabricator.fb.com/D342789
was that we should update the Hackbook iOS sample app to show developers how to
process data passed back from the dialog. Changes were made to use
dialogCompleteWithUrl: instead of
 dialogDidComplete: method. Other tweaks made to display a success message back
to the user when an app request was sent. Also NSLog the post_id and request_ids
information so developer can check these out.

Changes still need to be made to the iOS SDK docs
(https://developers.facebook.com/docs/reference/iossdk/FBDialogDelegate/) to let
developers know how to handle the dialog data in the callback.

Test Plan:
1/ On iOS simulator 4.3 ran through the Publish Feed and Send Request flows.
Checked it works and shows the proper user messages and debug messages (that
developers could use in the future).
2/ Tested on iPhone 5.0 and tested feed and app request dialog flows.
