Hmm, that's not what I have in mind for {$BaseName} -- as I'm
envisioning it, {$BaseName} will return the name of a page without
any suffixes.  I wasn't thinking of doing anything with prefixes ...
but perhaps I can add this capability as well.

Essentially, an administrator and/or recipes will define 
suffix (and prefix?) patterns that {$BaseName} is to remove or
change.  So, for example, to define "-Talk" as a suffix to
be removed in {$BaseName}, we would define:

    $BaseNamePatterns['/-Talk$/'] = '';

So, I guess it's not too difficult to get basename to strip off
prefixes as well:

    $BaseNamePatterns['/^Data-/'] = '';

Regardless of how we define it, {$BaseName} will work in
pagelists by using {=$BaseName}, {<$BaseName}, etc. in the
pagelist template, the same way we do it for other page variables.
