Title: Added method to display a request dialog

Added a method to display a dialog to invite app request to friends.
This is actually a wrapper of the ```-dialog:andParams:andDelegate``` Facebook method.

Implemented the ```-dialogCompleteWithUrl:``` method of Facebook delegate to handle the response after sending the invites and to retrieve the ids of the invited friends.
