Bug fixes & misc:

- Follow up 7fd6776, correcting how to make player sit by autotrade persistance. - Follow up 7fd6776, pc_setstand() does a check if player can stand or not. - bugreport:9174, buyingstore_close() doesn't clear buyingstores data on table. - Fixed "missing" buyingstore search (purchase type search) in searchstore, by adding DBMap *buyingstore_db. - Added nullpo checks on some buyingstore.c functions. - Added do_init_buyingstore() and do_final_buyingstore(). - Failing autotrader from pc_setpos(). (Since autotrade doesn't have 'fd'? FIXME later) Signed-off-by: Cydh Ramdh <house.bad@gmail.com>
