I upgraded all plugins I could see except org.ysb33r.doxygen. 2.0 made
breaking changes, and I couldn't figure out how to migrate.
Most of the changes are for suppressing new linter purification rites.
This is necessary for modularization.
Move the wpilibj CameraServer classes to the cameraserver package.
Move the edu.wpi.first.wpilibj.vision package to edu.wpi.first.vision.
To avoid code breakage, add deprecated copies of the wpilibj classes to the wpilibj jar.
