Fixed Display on Windows

Works well on Windows 7 at least.  Haven't tested on other versions of
the OS, and it's likely to not be the most platform independent
solution, since we depend on Windows Photo Viewer auto-updating the
display.
OpenCV for everyone!  Also make it faster

Initially we used OpenCV just for face detection, but it turns out the
libraries are much more full-featured than we realized, such that
virtually all of our image processing can be performed within the
library.  This update completes the transition to fully using openCV
across all platforms.

Performance improvements. Added Diagonal Movement, replaced clear frame
buffer functions with separate thread for loading images.  Screwed with
timing
Sweep, Guard and profile mode

added new modes for the turret behavior to sweep the range or hold a
position.   Added option to enable detection of side profiles of faces,
which is much slower than full frontal faces only.
tried to standardize across different launchers, but untested on the
launcher1130 so it may not be centering where we want.
