Pressing F5 at A Plugin Tab Triggers Error KCHAPI6001E "Invalid URL. Redireced to home page."

When I tried to add a plugin tab to kimchi, I found a problem when I refreshing at my tab page.

If I press ctrl+F5 at the tab page add by my plugin, it says "KCHAPI6001E Invalid URL. Redireced to home page." and redirects me to the front page. I did a little
debug and found that it's a AJAX timing problem. When loading the page, it calls kimchi.listPlugins to get the available plugin list from the back-end then it updates the tabs. However the listPlugins is called asynchronously, and needs some time to finish. So when the refesh action triggers an redirect event and calls onKimchiRedirect to redirect to my plugin page, the plugin tabs are not loaded yet. So it redirects me to the front-page instead.

I am able to overcome the problem by adding "async : false,"
in ui/js/src/kimchi.api.js to listPlugins

    listPlugins : function(suc, err) {
        kimchi.requestJSON({
            url : kimchi.url + 'plugins',
            type : 'GET',
            contentType : 'application/json',
            dataType : 'json',
            resend: true,
            async : false,
            success : suc,
            error : err
        });
     }

I'm bad in js, maybe you have a nicer solution.

Submit a patch to add minimal UI for the sample plugin, so that you can easily reproduce the bug.
