Various JavaScript fixes

  * Syntax error fixed
  * lock refresh event is now attached to the whole edit form since it bubbles
    up and we cannot be sure that the wikitext input exists on all edit forms
  * Updated findPos(X|Y)
  * Easier and less error-prone way of getting the section edit button in the
    highlight mouseover event handler
