	/* Topic: Theme Loader
	 *
	 *	To use this loader, just define GLOBALS['thyapi']['theme'] in the form:
	 *
	 *	array( 'name' => <theme_name>, 'custom' => <dir> );
	 *
	 *	<dir> can be a string or an array of strings
	 *
	 *	Every css will be parsed and included on a single output, which will
	 *	be cached by browser.
	 *
	 *	The suggestion is to create a PHP file, with the needed definitions
	 *	and include this file, placing a:
	 *
	 *	<link href="<your_file>" type="text/css" />
	 *
	 *	In your output to the browser.
