[quangtam]

Implement new option to display browser progress status bar (ios & android) Here is new options:

browserProgress: {
        showProgress: true,
        progressBgColor: "#007e9c",
        progressColor: "#FF5E00"
      }

This is working perfect. Waiting for it to release and I'm using it right now.
