Reorganized build system for bot3 code.

- Put all the robot-specific code for bot3 in a directory called bot3.
- Remove unecessary executables from start_list.txt and atom_code.gyp
for the third robot.
- Get rid of Vision2009 from WPILib. (Nothing seems to be using it,
and gyp was throwing a hissy fit about duplicate names between that and
Vision.)
- Update .gitignore for third robot code.
- Modify build.sh files to allow us to build the third robot code.
