String interpolation based styles

[roman01la]

Perhaps this could help someone who wants to transition from plain CSS into CLJSS. The idea is to be able to paste in existing CSS such that it would still work.

Cuerdas library has a nice macro for string interpolation which can be used in this case. It could look like this:

(deftyles button [font-size]
  "border: none;
   font-size: ~{font-size}px;
   color: #fff;
   background-color: blue;")

Or maybe we could do just fine with this

(defn button [font-size]
  "border: none;
   font-size: " font-size "px;
   color: #fff;
   background-color: blue;")

The latter would preserve syntax highlighting.
