FS#30773: put exact matches at top

There have been a few proposed solutions to this, but there really isn't
anything without a drawback. Things break pagination, require loading
the entire result set from the database, etc.

Just plop a new table on the page if someone did a so-called "simple"
search and we have a match. Only show on the first page of the search
results. This results in a relatively fast experience for someone doing
something like searching for the "perl" package.
