Currently all the FRCVision customization is done as part of stage2. This will make merging changes from RPi-Distro more difficult than it need be. The build infrastructure is designed for multiple stages, so these bits can mostly be moved to a (new) stage3.

Revamp image to build dependencies as part of stages (#83)
c85fd9f 
Fixes #17.

Stage 2 is fairly minimal, stage 3 builds/installs OpenCV and WPILib et al, and stage 4
builds/installs the FRCVision webdash and adds the vision examples.

Other changes:
- OpenCV compiled with ffmpeg, OpenBLAS, and libgtk (fixes #79, fixes #80)
- OpenBLAS added to image (fixes #65)
- C++ Makefile is more easily extensible (fixes #71)
- Sources for everything are bundled into image into /usr/src
- README updated (fixes #16)
- pkg-config files for wpilibc et al are now installed and C++ Makefile uses them (if compiled local to Pi)
- Both dynamic and static libs are included in image

The only downside of all these changes (particularly the ffmpeg, OpenBLAS, and libgtk inclusion)
is the image size is now over 3GB (800MB compressed). The previous image didn't quite fit on a
2GB card however.
