Implemented the "Arrange Items" Storage feature (merge & sort items on the Storage). Fixed items from different ownerships being merged together when trying to swap their positions. Fixed a bug where putting equipped pets onto Cash Shop inventory would cause a crash the returning to the game.
Changed map chair bonus healing mechanic to be a player skill, instead of promptly available for all players (healing buff takes place only if the player has the skill). Hired Merchant now properly checks for a space on the inventory before permitting a player to buy an item/bundle. Minor fix with concurrency on MapleStorage.
Added experimental autosaver feature. Fixed pet ignore feature not
saving/loading data in some cases. Added concurrency protection for
inventory classes and monster book.
Implemented EXPERIMENTAL DBCP (connection pool), trying to improve
concorrent access to DB. Added door portals on Kerning Square. Fixed
equipments getting stat overflow when upgrading stats. Fixed expiring
pets crashing the client in some cases.
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).
