When generating from Jade, package.json is missing ng-html2js dependency #1722

I'll try to put up a PR at some point for this but if I can't get to it and someone wants to fix this quickly, here it is. When you generate with the Jade option, the Karma.conf file still keeps the config for ng-html2js for any html files that may be present. So we should add the ng-html2js dependency to package.json always.
