Fixed: Popup in Safari won't open after closing it programmatically

Popup closes itself programmatically after five seconds when clickhide is being activated. However, unlike Chrome, Safari has only one instance of the popup running which window.close was closing. Therefore when clicking on the icon again, Safari was unable to open it and crashed.

File safari/ext/popup.js (right):

safari/ext/popup.js:20: window.closePopup = function()
This should go into the ext namespace. However since we import ext from the
background page, I suggest following code:

  window.ext = {
    __proto__: backgroundPage.ext,
    closePopup: function()
    {
      ...
    }
  };

Done.

This has to be changed to |ext.closePopup| too.
