[#38] Adjust base jQuery

* Remove jQuery that makes
  'other' elements react.
  Only mouseover'd and
  mouseoff'd elements react.
  This has greatly reduced
  the lag of the header links.

* onmouseover, header link
  goes to a deeper shade of
  red and increases its
  height.

* onmouseoff, header link
  returns to normal shade of
  red and normal height.
