First feedback and update

Updated wowmapper today, changed some things, (hopefully) fixed some bug related to 32bit and 64bit systems, thanks Ryns. Also added a sample to generate tiles with a little border so you have perfectly prepared data for Recast. Hope you like it!

Update:

Seems like a little bug survived, though no big one as Ryns told me (again 32/64bit stuff). I think I have to install some 64bit linux in VirtualBox and next time make tests myself beforehand. Other than that it seems like you 64bit guys are ready to go too now.
