Step to reproduce:

1. Make a structure like this:
   XXXXXL
   B
   where L is cage lamp, facing the X direction (attached to the block X)
   X is any solid block
   B is mechanical bearing from Create
2. Turn the mechanical bearing by 90 degrees
   See the cage lamp is not attached to the solid block X anymore (and still face the same direction as it was first placed)

In fact even I break the solid block the lamp attached to, the lamp does not fall off.

setup:

after turn 90 degree

Catwalks stairs, catwalk railings, and hulls also do not rotate. This also happens when using trains and disassembling them in different orientations. It's quite frustrating when using the blocks for trains.

OK then it should all be those blocks lacking a rotate() method.
