No need to actually check message contents.

@janeznemanic, how about this?

I got to thinking, and there isn't really a need to check the message contents against the pkgdb acls.

When we run ``/usr/local/bin/genacls.sh`` once, it regenerates the local acls cache for *every user* and *every package*.  So, if the acls don't match for one message or another, it doesn't actually matter for the ``genacls.sh`` script itself -- it will just go query pkgdb on its own to get all the correct information.

Furthermore, if we have queued up 16 messages while delaying action, we just want to run genacls.sh once, not 16 times (I think).
