Event disposing patch + Papulatus rework + V. scroll exploit patch

Solved issues with PQs/events in progress not disposing properly party leavers (warping them out of the event maps).
Solved issues with cleared PQs/events disposing players unproperly when leaving or disbanding the party.
Reworked Papulatus battle now working as an event instance, similar to how Capt Latanica battle is dealt.
Fixed a possible PE exploit with Vega's scroll.
