Add additional retraction before second auton fire.
Add ball-dragging two-ball auton

The new auton lowers the acquirer onto the second ball and
drags it in this manner to the firing point.
Fix compiler error from previous commit.
Add doublemobility auton for 2-ball donation

Also move auton40 to the end of the autons.
Ensure CV and DV autons open before waiting

Also modify shootIfHotCV to only shoot, not extend.
Fix tabbing in auton34()
Add delay in dumbfire autons for ball settling
Debug auton34
Add longer drive time for two-ball drag
Reduce AUTON_TIME_TO_LINE_UP_DRAG_SHOT to 1.00
Implement shooter.fireBallPastBackdrive

This function runs the chooChoo for a short period of time to
ensure the limit switch is pressed, then fires the ball using
standard logic.
Modify auton34 to prevent backdrive on second ball
Modify fireBallPastBackdrive() to avoid constants

New fireBallPastBackdrive() retracts and then immediately fires,
hopefully minimizing backdrive by reducing idle time between
retracting and firing.
