Added true protection against race conditions on player trades and fixed
some situational issues. Character's quest status table also received
concurrency treatment. Quests with time limit now expires properly.
Increased subtly the performance on the server start-up.
All Guild Alliances system is now functional. Tweaked guilds in order to
sync MapleGuildCharacter objects that were supposed to be the same when
being accessed from both MapleGuild and MapleCharacter classes.
Completed (hopefully, now!) implementation of automated modules for PQ
scripting. Added HP bar for some bosses that wouldn't display it before
(like King Slime, Alishar and CRog).
Introducing BRPQ rewarding system (KPQ/LPQ clear-like) and patched
issues regarding "no apparent party leader" after party leader
disconnects and reconnects.
