revert to REST

DATA API started returning html body for a comment instead of the text
body. This broke everything in this app. This is a quick fix that uses
the rEST api to accomplish was the DATA API did. This also makes the
refactoring done for the DATA API wasteful and inefficient, yet
unnoticeable given the small amount of processing needed in the first
place.
Finished reversion to REST API

A bit of janky work done here in reaction to changes made to ZAF.
Enough to make sure hopefully that everything will work now. Testing
this branch until I can be sure all previous issues have been fixed.
