Bug Fixes:

- Failure when initializing autotrade persitance for PACKETVER < 20120201 or NEW_CARTS, ENABLE_SC_SAVING aren't defined - Added 'feature.autotrade_open_delay' config at conf/battle/feature.conf to give delay to open vending/buyingstore by autotrade persistency (bugreport:9077) - Add immediate save after vending/buyingstore opened to avoid missing sc_data (for SC_PUSH_CART) when server terminated before saving routine (bugreport:9077) - Disable to trigger NPCE_LOGIN (and NPCE_LOADMAP?) for autotraders, avoid vending_reopen & buyingstore_reopen failure (bugreport:9077) - Set player's state, 'monster_ignore' when autotrade - EXP calculation overload (bugreport:9127) - Added macro apply_rate(val,rate) & apply_rate2(val,rate,per) Thank you all for reports & helps Signed-off-by: Cydh Ramdh <house.bad@gmail.com>
