Move Review Board's propertyUtils.js into Djblets.
Review Request #6159 — Created July 28, 2014 and submitted
The config form code was trying to call out to $.bindProperty, which was
in Review Board's propertyUtils.js. This change moves that codebase over
into Djblets, renaming it to jquery.gravy.backboneUtils.
Saw the new unit tests, which passed.
Removed the old code in Review Board. Tests still passed.
