Rebalanced the way equipment exp is gained (about 100~200 same-level
range mobs to pass equip level 1 to 2). Fixed reactors dropping quest
items to player if they don't have the quest started. Fixed broken
Temple of Time quests.
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).
