Title: [imp] Add the ability to use a custom.css with Protostar.

Currently it is impossible to use a custom.css file when using the Protostar template. A search on the net always ends up with a core hack of the index.php file, which could result in a problem when the index.php is being updated in a Joomla update.

This change checks if the file custom.css exists and if so, load it.
