Support for other external shares

[RailsViceRoads]

Thank you for reactivating this app.

Is it possible to extend the app to modify other external shares? In my case it will be mainly the Polls application and some times the Forms app.

In my case I am wondering whether it'd be possible to make it work with Calendar app.

And Memories. Would love pretty URLs for shared albums.
