Slabs not aligned with blocks

[rlf]

What steps will reproduce the problem?

1. Try to create a simple door using the pathwand
2. Use the REVERSE_TOGGLE animation
3. Add a button to the mix
4. Toggle the door
5. It will leave a small gap when the door is closed :(

What were you expecting to happen? What happened instead?

That the TOGGLE animation would leave the "slab" at the exact block-coordinates, making the plugin useful for complex doors etc.
