This adds the ability to pass multiple properties to the box-shadow and transition mixins (without having to pass an escaped string). It also adds a text-shadow mixin (with the same ability)
For example:
.box-shadow(1px 1px 0 rgba(0,0,0,0.5), inset -1px -1px rgba(255,255,255,0.5));
In short, when passing a single parameter to a LESS mixin with no arguments limit (e.g., using "..."), it will insert commas for every space character found. Thus, this implementation registers a default value for the second parameter (while still allowing 2+) and filters out the default value when parsing the @arguments variable.
See this post for a full description and reasoning behind the @arguments parsing and regex'ing: http://www.toekneestuck.com/blog/2012/05/15/less-css-arguments-variable/
