Add grunt-uncss task to remove wanted CSS classes

[tommaton]

Would be nice to use grunt-uncss (https://www.npmjs.org/package/grunt-uncss) to remove all unnecessary CSS classes to make it even more lightweight.

I've used it on a couple of sites with great success, the latest compiled Kickoff framework CSS from 89.43kb --> 44.76kb

Could definitely be a good thing to add and something we’ve talked about a couple of times.

Will look at adding when I look into the other grunt updates.
