Changes From Workspace

Conflicts:

Gruntfile.js fix

switch back to original glob
Adjusted Pagination

* takes pagination styling out of `_global.scss`
* adds pagination folder and `_pagination.scss` to module folder

* @imports `modules/pagination/pagination`
Pagination Styling

Category Count Number
