Adding extra icons for Chrome and IE/Metro app

There is a duplicated &lt;link rel="shortcut icon" type="image/x-icon" href="favicon.ico" /&gt; that is just copied from Google Reader. I guess it is preventing some buggy browsers from using higher resolution icons to be used instead of .ico icon for favicon but remove it if doesn't make sense for you. It is cool if you provide a vector (.svg) version of commafeed so it will be easy to make commafeed icon in any resolution easily and safely.
