bug 842215 - some tweaks to improve performance

1.remove initial animation on toggles
2.remove extra device states queries from media_storage.js
  because these states are displayed only on the sub-menu which
  is lazy-loaded
3.icc menu should be default visible to prevent extra reflow. (Most
  of the time, we have a SIM card in the phone, the menu has higher
  probability needs to be displayed.)
4.Don't track mousemove targets in Settings (patch from Chris Jones)
