PHP helper functions for using mod_concat.
By default, the stylesheets and scripts functions return the normal
<link> and <script> tags for each filepath.
>>> stylesheets(array('one.css', 'two.css'), array('media' => 'screen'))
'<link rel="stylesheet" type="text/css" href="one.css" media="screen"/>
<link rel="stylesheet" type="text/css" href="two.css" media="screen"/>'
>>> scripts(array('one.js', 'foo/two.js'))
'<script type="text/javascript" src="one.js"></script>
<script type="text/javascript" src="foo/two.js"></script>'
If 'MOD_CONCAT' is True, the file URLs will be joined with a comma and
linked in a single tag.
>>> stylesheets(array('one.css', 'two.css'), array('media' => 'screen'))
'<link rel="stylesheet" type="text/css" href="one.css,two.css" media="screen"/>'
>>> scripts(array('one.js', 'foo/two.js'))
'<script type="text/javascript" src="one.js,foo/two.js"></script>'
