Added Relay m_ShooterCyls, and SetShooter(bool) method to PneumaticSubsystem.
SetShooter sets the state of the relay depending on its argument.
Added Shoot command that toggles sets the relay to forward for one second, and then back to backward, and associated this command with the A button of the driver stick.

Moved initialization for drive subsystem into new init method, which will now be called by RobotInit().
Drive subsystem now enables encoders.
Added SetEncoders command to enable/disable encoders, based on its template argument.
