Changes:

1. Removed all dialog artifacts
2. Added the contextual nature of the comment CAB to take into account the
comment status type selected. This will work nicely in the case that you
modifiy a set of comments as the comment set will still be active after
the data model is updated and the CAB will update accroding to the status
of the comments in the selection.
3. Added icons for Approve and Trash/Delete from the iOS repo.
4. Clean up prep for rebase.
5. Fixed a good portion of the overdraw.
