Looks like Oliver added this yesterday to the recipe page, as I'd
forgotten to do so when I updated the recipe a few days ago.

Haven't done any actual testing, but in use it doesn't appear to have
any noticable effect on page rendering. There might be a very slight
slowdown from the extra class instantiation as $WikiDir is
overwritten, but otherwise read operations are of at most equivalent
complexity with those of PageStore. Some overhead is incurred when
writing pages to file (ie. saving edits) as a second copy of the page
needs to be written to wikitop.d, but in use I don't notice any
difference. Similarly there's a chance of a very slight slowdown when
reading pages for which there is no entry in wikitop.d, as the script
by default automatically generates one. Again, in use, I haven't
actually noticed this happening.
