New Vector feature: grouplink in pagetitle (breadcrumb)

Look up at the top of this page, and you’ll see, above the title of this post, a “Blog” link. This is a new feature of the Vector skin (in use here on OborWiki); it adds a link to the group of the current page above the pagetitle (a form of breadcrumb navigation, in other words).

To enable this for your wiki, add the (:titlegroup:) directive to:

• any page on which you want such a link to be displayed, or…
• the GroupHeader of any group where you want such a link to be displayed on ever page, or…
• the Site/AllGroupHeader page, if you want such a link to be displayed on every page.

There is also the converse markup, (:notitlegroup:), which you can place on a page to disable the pagetitle grouplink for that page only (i.e., if you’ve enabled it for a whole group or for your whole wiki, but don’t want it to display on a particular page).
