* Once again no longer applies to single inputs (this is a bit simpler, but I'm open to new ideas) but the entire set of inputs, labels, and help text within a particular element. However, the styles are not too dependent on markup or layout, so they're super flexible. * Simplified the markup in the validation docs examples to match latest changes. * Renamed `.form-state-validation` mixin to `.form-control-validation` to match naming of prev commit.
