As reported by J0k3r613, patched guild system not recognizing properly
the guild leader just after creation. Patched many more issues related
to guilds and alliances.
Fixed a bug on guild creation process where the leadership would not be
assigned instantly to the guild leader (would need to change channels or
reconnect to take effect).
Added the PIN feature. Fixed ranking now calculating ranks now
world-based instead of overall. Rebalanced equip exp gain and made
cosmetic equipments no more leveling up (cosmetics leveling up are
useless).
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).
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.
Fixed a issue on server delaying whenever a player gets a new card for
the mobbook. Some code refactoring unifying the several item picking-up
methods on the project.
