Issue: H=1

In over 8 months of the mod's public release, and 3 years of its development, the H=1 tag has been a mystery (except for some brief mentions in forum posts as to what we intended to use it for). I suppose it's time for the "surprise" now.

In NuWiki, there was a forum type that allowed the second post in an article to be treated as an additional article post. This never really worked in VaultWiki because it would require rewriting how all the caches and revisions etc worked.

H=1 will be used to split the article post visually into what looks like multiple posts. The segments are stored in an array which would allow admins to write and apply the only plugin I could ever see being useful in a multiple-post article - hiding additional content in the same article from unregistered or unsubscribed viewers.

If anyone can think of other uses for split-post articles, we might be able to organize some time to create a nice library of possibilities for this feature.
