Title: Stub getBackpack() in MediaInfo, move some checks

This change involves both the scratch-flash and scratch-flash-online repositories.
This allows more code to be shared between the online, offline, and open-source editors. This also fixes the 'duplicate' menu option being absent on costumes in the offline and open-source editors.
