automod orga (#494)
Several more package extractions.
These are all the easy ones -- flagstore, cachestore, setstore,
directory -- all get yanked out in the same way as countstore already
was.
These didn't cause any major changes to package graph overall, it just
makes the main automod package smaller (yay). Near future targets are to
try to tug engines and events a bit further apart, and that might be
more complicated, so I thought I'd put up the easy-to-review diffs
first.
