aTbRef updated info on Quick Lists

[Tip of the hat to @dmrogers for bring this issue to my attention]

There are some older corners of aTbRef where things survive longer than they should. So $AutomaticIndent was a thing in pre-v6 days but the attribute is now moribund and I’ve pulled links (3 or 4 pages) to it. IOW you shouldn’t accidentally come across that attribute’s page by accident (deliberately not linking to it her!).

As a result I’ve removed confusing info from the page on Quick Lists (quick in-$Text mark-up for HTML lists) and updated the Quick Lists page.

N.B. The zip of the TBX file online in not updated as a number of notes are in mid edit.
