stereo-cam: mounted on test platform

After a little fine-tuning of the aluminum brackets on the mount I was able to attach the stereo cameras to the test platform. It is now time to go gather some data at the local park and get the visual odometry working with the new stabilized mount. The calibration should be much more consistent with a rigid mount. The two camera's frame clocks are hardware linked via some soldering from 'vsync' to 'fsin'... not show in photo, as it is inside the case.
