Add the 2014 C++ vision classes back in

Most of the old vision code still compiles with minimal changes. I haven't
tested it extensively, since the AxisCamera class isn't done, but it
should work, as it was barely modified.

Java bindings are still TODO, since they used some JNA stuff that probably
won't work now.
