refactor(client): Replace modernizr with html5shiv and a short test for js and touch screen.

* Replace modernizr.js with a much smaller env-test which tests for js and touch screens.
* Remove all of the modernizr dependencies.
* Reorder bower.json to be alphabetical.


Note - IE is currently broken on master, see #1095. With #1097 applied, IE9 looks great.
