Fixed Bug#585 (http://bugs.zpanelcp.com/view.php?id=585) Theme manager can now select and use alternative CSS files.  Global CSS files like Bootstrap are now moved to gloabl-css/ folder as the CSS folder is read and displays all available CSS theme files.  Other minor tweaks to make this all work as it is supposed to.
