Title: Media query mixins

This covers the majority of media queries present in bootstrap except for

* print queries
* queries that need the word 'screen' i.e carousel.less, jumbotron.less, and tables.less
* anyplace where @grid-float-breakpoint is used to set the parameters of the query

Print queries will be super easy if we just add another mixin.
For the second and third cases - ideally you could override these defaults without having to add new mixins. Still looking into that.
