Meta-Mesh

OK, here we go: I finished some basic framework for meta-mesh in my personal develop branch of blender. It is just MetaBalls directed with mesh. It behaves as next subsurf type. It stores polygonized surface in displist of Mesh data structure ... not in object data structure. It means, that this mesh object can't be blended with other "meta-mesh" or MetaBall object. It was coded with this design, because it lacks some hackish construction, which MetaBall objects still have. I like this part of MetaBall code, because it is only "my" (I needn't use some inherited hackish code, which is hard to change or mantain). It is simple and clear and it is rock stable :-). I hope, that we will be able to use it in 2.36 version.
