• Add a bit more detail to a couple of docucomments in db-update.pl
• Drop and recreate the modtime trigger on the allocations table when doing the database update. This preserves the *real* modtimes, instead of generating an entirely artificial one that has nothing to do with changes in the actual IP assignment data.
