added lessify, css to less compiler

uses parser from lessphp to recursively describe a css file as a less
file. Looks for common ancestors in selectors and builds a less
document.

For now:

	./lessify filename > output

or, include `lessify.inc.php` and:

	$l = new lessify($file);
	echo $l->parse();
