Found & fixed World Studio texture alignment error in export

I fixed an error which would sometimes cause textures to be misaligned in the exported .dif file, especially if special texture alignment was performed. If you don't want to wait for the next version to be released, go ahead and download the updated plugin here:
www.leadwerks.com/post/map.dll

Just place the dll in your "plugins" folder, and get rid of any old .map plugins.
