Add Full Auto deploy

[jhajel]

Auto Deploy will release the climber.

The calculated ticks per distance should be (2048 48)/ (1.9 pi) but it is bit too high. We should play with this on Wednesday.

Ok, I've been thinking about this a bit. Here is a potential algorithm:

• on enable store the starting position (ticks) of both the left and right climber motor
• Pass these values to the auto deploy and auto climb constructors (maybe manual climb/retract as well)
• Don't allow the arm to go below starting position or above the starting position plus 16"

Also, for the auto deploy it should be

1. Upper arm move 8" up with a timeout of 1 second
2. in parallel move upper up the remaining 8" and the lower the full 16"
3. Optionally, engage brake

Also, check the speed of the climber motors and bump up as needed.

Nice job!
