switching testContactGrad test to use numerical.  but it still fails (occasionally).  added more debugging tools to help; it looks like the problem might be real
shouldn't have checked in the gradTest (not good for the build server)
fix getInitialState logic bug found by michael
grep found a lot of places where we were handling the state constraint case but not handling the unilateral constraint case.  added errors where appropriate
fix typo
another unilateral constraint check
adding known issue
fixed time-stepping gradient computation for position control case
Check for 'package://' syntax and warn once

URDFRigidBodyManipulator presently does not support the 'package://' syntax for
specifying mesh filenames. Rather than spam the user with a warning for each
mesh file, we now warn once per urdf that uses that syntax.
Re-enable building of urdf_collision_test

Also fixes the executable name in the usage message for urdf_collision_test.
