    Bug 13047: Updater should not send Kernel/GTK version
    
    Removed the %OS_VERSION% component from the update URL and replaced the
      /update/ component of the URL with /update_2/.
    Added support for minSupportedOSVersion, an attribute of the <update> element
      that may be used to trigger Firefox's "unsupported platform" behavior.
      Older versions of TB will ignore this (unknown to them) attribiute.
