gitignore:
* Ignored NUL which receives console output of TTS

DogWormVRC3:
* Added "deg" option to set the gravity vector
* Added test-to-speech to announce when a test has finished running
* Added a function to get the "pitch" and "roll" effect of g on the robot
  (since the IMU doesn't register the change in g)
* Started working on "responses" in general, slope response in particular
* Extended the arms backwards when the slope is increased during tests
