Group bad transform fix

Group objects were resetting their transform every time a child entity
changed, which would lead to situations where child entities would not
have their position and rotations restored correctly. This seems to fix
it, but need to do more testing.
Fixed rotation bug

Old code only checked immediate parent, but for this check to work
properly you need to walk the whole tree. This manifested itself when
rotating the large parent child example with the children wiggling away
from each other.
