Fixed slotMax function caching up dirtied player data.
Fixed many portals not supposed to warp players to "random spawnpoints".
Fixed Wind Walk not being cancellable by attacking.
Added Water of Life. Fixed Shuang (GPQ) npc dc'ing the leader when first
trying to enter the waiting area. Fixed some cases with the revamped
buff system, that would not properly check for the best buffs in some
scenarios, and would throw exceptions, caused by not properly protecting
access to critical data.
Completely rearranged buff system (system can smartly check for the best
statup to take effect for it's duration, or the server can be flagged to
act as usual). Refactored scheduling system for buffs expiration and
cooldowns to use one single thread per player rather than one per
instance.
Added mechanics for the EXP/DROP cash coupons (such as enabling
out-of-time active coupons via command and automatic update of active
ones over the designed interval). Created MapleCouponInstaller as means
to gather info about the coupon intervals and rates from the WZs (the
generated SQL table is already updated on the db_database.sql file).
