Implemented dynamic and multidimensional array support in RNA.

Example code: http://www.pasteall.org/7332/c.
New API functions: http://www.pasteall.org/7330/c.

Maximum number of dimensions is currently limited to 3, but can be increased arbitrarily if needed.

What this means for ID property access:

* MeshFace.verts - dynamic array, size 3 or 4 depending on MFace.v4
* MeshTextureFace.uv - dynamic, 2-dimensional array, size depends on MFace.v4
* Object.matrix - 2-dimensional array

What this means for functions:

* more intuitive API possibility, for example:
  Mesh.add_vertices([(x, y, z), (x, y, z), ...])
  Mesh.add_faces([(1, 2, 3), (4, 5, 6), ...])

Python part is not complete yet, e.g. it is possible to:

MeshFace.verts = (1, 2, 3) # even if Mesh.verts is (1, 2, 3, 4) and vice-versa
MeshTextureFace.uv = [(0.0, 0.0)] * 4 # only if a corresponding MFace is a quad

but the following won't work:

MeshTextureFace.uv[3] = (0.0, 0.0) # setting uv[3] modifies MTFace.uv[1][0] instead of MTFace.uv[3]
