color as function

[jtousek]

I've found this little bug.
LESS input:

.color { color: rgb(0, 0, 0); }

CSS output:

.color { color:rgb(0,0,0); }

expected output:

.color { color:#000000; }

I'm not sure where is the right place to call $this->funcToColor($func);...

Now I believe it should be at the beginning of compileValue method like this.

  function compileValue($value) {
    if ($value[0] == 'function' && $color = $this->funcToColor($value)) {
      $value = $color;
    }
    //...
  }
