List of things I fixed:
old << style messages didn't do crap, replaced with to_chat
Medidog now respects your vore preferences also.
K9 referenced the wrong type of sleeper unit by name, fixed now.
All do_after checks now also have a check for distance once the timer is
up.
All do_after checks now properly sets target = <thing to target>. This
is probably making the previous thing on the list redundant, but an
extra sanity check isn't a bad idea... I think?
