Performance: store object types for static objects in voxels.

[mklingen]

We currently only query the octree for objects directly. Most of the time this is very wasteful. If we just stored object types in voxels and only queried when needed, we could save a lot of our performance overhead that planning uses. Most of the time knowing the exact identity of an object (as opposed to its type) isn't even necessary.

No, It should still be done sometime, I just don't care enough to make it work right now.
