* output some warnings only in debug>=1 mode
* made spellcasting with no target possible
* fixed exception when the server sent an object_update packet for an object that just got deleted; the rest of this packet got skipped then. this is now fixed; PseuWoW guesses the original object type and can now handle these packets almost 100%.
* fixed possible crash when handling emotes. thx Sesk for pointing out the problem.
* need to remove lots of debug output later, after bags are done.
* fixed ObjMgr. better store objects in only 1 list instead of storing them in 1 list per type.
* eased config: if you modify the conf files during runtime, just type "config" in the console and the changes will be applied.
