[builder] components classes w/ creator

WIP #221 - Will allow us to delete many binary .blend
files and save aprox. 8 MB

Modify the test with those new classes,
move Human to morse.builder.robots.human,
set_blender_object w/matrix_parent_inverse.identity
  -> fixing GPS pose relative to ATRV (z=+0.10)
clean PassiveObject class

was trying to get an instance from componentDict in init, while at this
moment of the simulation, the Kuka actuator might not be instantiated
yet.
