Move and bump JSHint dependency

- Fixes target so it is also actually run.
- Fixed JSHint failure due to calling "use strict" in the wrong place. Since the file is run in node only, strict is already assumed.
Merge branch 'move-jshint-dep' of https://github.com/nschonni/grunticon into nschonni-move-jshint-dep

Conflicts:
