Parallax/Normal mapping support added to static batches

Been working on upgrading static batch elements with some shaders currently to make the maze parts looking good. Started with a new column with diffuse / normal map textures by Zphr. He used blender to model a high polygon column and then with the help of blender's baking and normal map facilities he created the diffuse texture and the normal map texture, and made a low poly undetailed version of the column. (After that seeing that the shader needs a specular map, I've created a very simple one out of the normal map texture by making it black and white and adding a bit of contrast to it.) Basic versions of a normal and a parallax shader of jME has been tailored to integrate into jClassicRPG. Check the screenshot, how low polygon walls and column can be made look more like high poly models with GLSL shaders.
