Always show "Reshare original" for link. Show number of reshares in the post_initial_info div.

This is to improve UX by making it much more obvious how to reshare a post that
has already been reshared.  Prior to this change, the link to reshare would show
only the reshare count, e.g. "7 reshares".  Most users would have no idea that
they need to click "7 reshares" to reshare the post themselves.
