Fix list numbering on Freedoms admin screen

[kpdesign]

The list of 4 freedoms on the Freedoms screen begins with 0, not 1. Issue has existed since that admin screen was introduced in 3.2.

Attached patch fixes Jane's request on original ticket (​#17383) to update the original <ol start="0"> code.

Also added "since x.x" to PHPDoc block.

I thought starting from 0 was deliberate, and Jane's suggestion was about replacing the deprecated start attribute with CSS. 19158.patch​ is an attempt to do this.

Why would you start numbering a list with a zero?

Because the FSF defines the four freedoms that constitute free software as "freedom 0" through "freedom 3", see ​What is free software?. I assume it starts at 0 because that's where computers start counting from, e.g. the first index of an array in most languages is 0.

I'm pretty sure that the start attribute is no longer deprecated in HTML5.

Indeed: ​http://dev.w3.org/html5/markup/ol.html#ol.attrs.start

It starts with 0 intentionally, because that is how FSF does it,. As we are liberally quoting them, we are following their system (even though Americans usually don't start from 0 in lists or apartment floors). We absolutely cannot change this to start from 1, and it's not a bug.
