MapleCouponInstaller + EXP/DROP Coupon System
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).
