Title: Share Dialog does not require Login or any extended permissions

Currently user have to have an active session with Facebook plugin to use **"Share Dialog"**, but Facebook documentation suggest *". This does not require Facebook Login or any extended permissions, so it is the easiest way to enable sharing on web."*

This Change just request an active session when developer execute a showDialog different than a share dialog
