* Move java lib install to /usr/local/frc/java
* Build and install both debug and normal OpenCV libraries
* Install OpenCV cmake files
* Build OpenCV Java with version 8 target
* Build static OpenCV for static allwpilib binaries
* Move netconsoleTee install to /usr/local/frc/bin
* Move multiCameraServer default app install to /usr/local/frc/bin
* Install more FRC binaries
* Fix /home/pi/zips/java-multiCameraServer.zip owner to pi:pi
