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.

f9762d63ab Removed many memoryleaks in Example Browser, reducing some technical debt. 
When running the Example Browser with Basic Example, 'visual leak detector' show no leak.
Many other individual examples still leak, so it is work-in-progress.
Disabled the profiler window (too many leaks)
