Need to be able to change shooter power

[lcook1218]

The shooter power should be controlled by the trim on the driver joystick.

right now the shoot() method runs:
triggerMotor.set(1);

this means the shooter will always launch the Frisbee at full power. To work on a solution, go to the main page and create a new branch. When you are done, submit a pull request to merge your edited code into the main project.
