Fixed an (quite amusing) exploit with map chairs stacking "extra healing" schedules on certain conditions. Fixed mini-dungeon not disposing players properly in some cases. Refactored the mini-dungeon structure. Fixed an issue on CASH inventory merging same items when trying to swap them. Fixed Beholder crash issue when trying to enter Cash Shop.
Reworked many aspects of the Malaysia/Singapore region (added DB data,
enabled Latanica & Scarga expedition, fixed maps). Fixed some issues
related with player warping.
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).
