Title: Improved .box-shadow mixins

Added .box-shadow mixins that take multiple arguments. This allows up to three comma delimited shadows to be defined without needing to escape the string with tilde and quotes. It allows variables to be within the box-shadow to be evaluated by LESS.

Before:
.box-shadow(~"inset 1px 0 0 rgba(255,255,255,.125), inset 0 1px 0 rgba(255,255,255,.2), 0 1px 2px rgba(0,0,0,.05)");

After:
.box-shadow(inset 1px 0 0 rgba(255,255,255,.125), inset 0 1px 0 rgba(255,255,255,.2), 0 1px 2px rgba(0,0,0,.05));
