Blender Git Loki

* added some missing tooltips
* made name string cleaning function allow chars ,.()[]{} in fbx model names
* clamped export lamp intensity to 200
* each mesh only links to the image-textures it uses. (before it linked to ALL textures)
* added support for AllSame mapping, this means when a material or texture only uses one, a single mapping index can be given rather then a big list with the same value in it.
* improved material and texture mapping method
