Title: Change to 24 columns, added scaffolding classes for 'lg' displays, update grunt* versions, added source maps options to Gruntfile.js and corrected the spelling of my name.

Absolutely stunned as first time I've found a use for IE. The Zoom function changes the reported window size, so zoomed out on a 1024x600 netbook display you can test 1200+ sized displays and hence the applied classes.
