714797 - Annotator text selection algorithm fails on various cases

Status: RESOLVED FIXED

I noticed that annotator example is failing to select text on many cases.
It works correctly on wiki pages, but except that, it fails because :
- `jQuery.text` method behavor. This method includes <script> tags!!
- the code assume that a parent node of the selection has an ID

In this pull request, I've implemented a better text selection algorithm, that doesn't use textContent nor jQuery.text in order to ignore <script> tags. I fixed the parent node assumption and removed useless `$`.

This pull request is on top of PR #316, from bug 714778. As it allows to make annotator example work again!

On the first hand, this patch looks like a bugfix that would be good to have in 1.4, but on the other hand, we lived with this behavior for many releases ...

Looks good, works well, r=@mykmelez.

This doesn't look very scary, but since it's very late in the cycle for 1.4, I think we should reduce risk as much as possible by waiting to ship this in 1.5.
