@himdel T minus 14 controllers and we should be able to upgrade to Angular 1.6. (14 controllers in this PR, that is)

I did a quick dry run with 1.6 and tried a few of my favorite forms, and all was quiet (as in, no errors)

Thanks for all the effort @AparnaKarve looks like we're finally rid of them all! :)
