26a464bf0b [URDF] Edit loader to handle full inertia tensor. 
Previous URDF loader did not handle off-diagonal elements
in the URDF. This commit adds functionality to allow
the loading of an inertia matrix that has not already
been reduced to its principal components. It diagonalizes
the inertia matrix, tests that the values are real and
updates the inertial frame.

7df9b69039 pybullet: add option to use NumPy to speed up, thanks to moof2k 
option is disabled by default. When using cmake, use
cmake -DBUILD_PYBULLET=ON -DBUILD_PYBULLET_NUMPY=ON
then both testrender.py and testrender_np.py will work
without numpy only testrender.py works.
The numpy.reshape is likely a no-op when using numpy array,
so we could remove testrender_np.py...

1c65cae6d0 [SharedMemory] Calculate inverse dynamics now uses world gravity. 
Small change that takes the world gravity and applies it to the
body during the call to inverse dynamics in the shared memory
interface. Otherwise the gravity vector is left at the default
value and there is currently no interface to set the gravity
for the inverse dynamics system.
