This commit contains several changes. First, the CodeMirror editor is now resizable, which is particularly useful for the tutorial page. The resizing requires jQuery UI, hence why that plugin has been added. Second, the 'view/edit soure' link is no longer shown for the source editing page, since much of that code is fairly complicated an not particularly useful for newcomers to the framework. Third, I've change the markup behind the 'View' and 'Controller' tab buttons to be more standard and to have a greater differentiation between the active and non-active tabs.
…d codemirror editor. "save" redirects to the view and controller you where coming from.
