Pull request [jasnell/w3c-socialwg-activitystreams] remove "Share"

remove "Share"
By jasnell 
The "Share" activity creates some confusion. In many common cases, a "Share" is really just a normal post targeted at specific people, which can be accomplished using the audience targeting mechanism along with "Announce". Removing "Share" allows us to eliminate a confusing element in the vocabulary.
