Get moveToAccel_multiple.ino working

In the timer branch there is a testing function that can be used to make sure OpenStage can run with hardware timers. i.e. the motors need to rum smoothly for the required distance, etc. See the associated milestone for details.

The first thing to do, therefore, is to make sure that the motor hardware runs correctly using this function. Once all this works, we can integrate the ideas into the main code.
