* few script changes; added new func "ScriptExists".
* started an extractor tool; using StormLib (thx to Ladislaw Zezula!). for now convert some dbc files to scp. more stuff will follow.
* some changes to the realm/world connect code; still needs a rewrite.
* support conf parameters for GUI (check conf/gui.conf/gui.conf[.default] )
* dropped now redundant and bloated SDL
* added the irrlicht files to the repository.
* NOTE: to compile PseuWoW now, you need to have the DirectX SDK installed, unless you disable build of DirectX 9 !!!
