Added DelayedEvent object so that I can spawn threads and then delete them before they execute. I was gonna include Stephen's EventHandler but I was feeling lazy. I'll probably incorporate it later on.

Added framework for creating effects and applying them. Effects are
constructed using createEffect(), which accepts the type of effect, the
source of the effect (the thing causing the effect, IE caster), and the
duration of the effect (which is set at creation). The effect timer is started when the duration is set.

Added effects attribute to CoreClassification. This will allow for racial
effects (and class, though I don't have any personal intention of using
that).
Removed inclusion/exclusion lists until I implement that junk.
