* Fix issues brought up in r75832
* Really and truly add in a couple files that were supposed to go in with r77898, and fully revert r77860 (which was a reversion of r75832). (Ran previous commit for r77898 from wrong directory. Oops.)
* Fixed issue with help box text not being parsed.
* Modified help system to remove tooltips and instead open/show hidden boxes.
  - I am not happy with this design and future revisions will iterate upon it.
  - The biggest problem is everything sitting "on top" of itself.  I dislike this a great deal and plan on changing it to be more aesthetic and natural; however, I wanted to get a version of this in that allowed for cut-and-pasting and solved the text parsing issue.
  - With javascript disabled, help text is visible by default.
* Remove redundancy in checkboxes
* Added i18n entry for "help", which wasn't there for some reason.
* Removed references to tipsy library in installer html
  - Kept tipsy library in core; this is being used elsewhere.
