 Simplify CSS rules for clearing floats and remove unnecessary older
 browser vendor prefixes.

  1. Consolidate the {{{:after}}} clearing selectors into one block, and
 change most elements to use the overflow property instead.
  1. Remove prefixed versions of border-radius and box-shadow since they
 are fully supported in these browsers now. Also remove older webkit syntax
 for linear gradients.
