I think the idea of journal entry triggers is great, but I also
think it's a bit of an overkill to always initialize triggers and
run all fibers through the cond. Would be ideal if we keep using
simple journal_entry objects for most cases and use journal_entry
with triggers only when we need these triggers. Would that be
possible to do? We could keep the trigger-related members in
journal_entry class, only initialize and use them strictly when
needed, or we could make a derived structure which contains the
trigger state and actions.
