      Description

      The uninitialization tag will enable components and pages to
      have custom javascript executed when the page unloads.
      I am aware of many use cases where this is useful, but here is one I recently came across:
      Assume that a StylesheetSwitcher component exists (it does ) which allows the user to
      change the skin of a web-app. It does this by providing special javasript links that do the work.
      However, in many browsers, the user can change the skin from the browser menu. Of course,
      this action does not trigger any custom javascript. However, if we could have some script executed
      when the page unloads, we could determine if the user has performed the above action, and
      act appropriately!

      I expect this new tag to be used just the way the initialization tag is used.
      Also, implementing this requires nothing more than duplicating the existing code that
      allows the initialization feature.

        Use dojo to trap the unload event and execute as much js as you'ld like!
