These folding arrows are based on the English Wikipedia setup, created
by Edokter. I don't see why all wikis can't benefit from them.
The only complication is with right-to-left languages, where ◄ is needed
instead of ►. I have updated the i18n file in a way that I hope is
sufficient.
When JavaScript is disabled, the fallback is a bit unintuitive, but no
worse than what is already there.

* 0 is falsy, cover for that case
* Add comments explaining the numbers, these come from PHP constants, via $wgCategoryTreePageCategoryOptions end up in data- attributes
* Follow-up r112849
* Use dashes versions of data attributes to make it easier to find them (now the data attributes as found in PHP where no where to be found in any JS file, appeared to be bogus)
* Don't create a new <div> element ($parentTag) only to store a single string in it's data object, using local variables for ctTitle, ctMode and ctOptions instead.
There's a couple of WTF moments in the code, this is really due to some issues with the PHP side of stuff. It really needs some TLC but for right now it works, I'll come back to it before 1.19 and clean it up.
