create standalone statusconversation view
Merge branch 'conversation' of https://github.com/cosent/plonesocial.activitystream into conversation
working rough prototype of conversation replies.
TODO:
- thread sorting in backend should not be reverse-time
- status input form should only show on active/selected statusupdate
- active statusupdate should be highlighted + extra actions
- only insert thread_id in backend getter if that id is not already in the result set
