Fix hogan js templates in IE8
Fixes: bug #1110226 Incorrect usage of the templating framework as the html should be provided and not text? Weird that it worked in other browsers though. As part of the fix hogan has also been updated to the latest official version 2.0.0 which may prevent other bugs. Upstream bug has been filed here: https://github.com/twitter/hogan.js/issues/130 Change-Id: Id5b6cef85dab1f9a497a525f9c065b410c52b38f
