Make Charge command speed and time dependent

[AndrewLester]

The speed of the charge auto and the amount of time it runs for should be specified in the Charge constructor. This means that the withTimeout method will have to be replaced by the following:

1. Have the Charge class extend WaitCommand.
2. Call the super class constructor with the time specified in the Charge constructor (e.x. super(timeout) where timeout is a parameter of the Charge constructor).
