Request Phase PWM support (aka Locked Anti-Phase

[GoogleCodeExporter]

What steps will reproduce the problem?
1. libqwerk doesn't support different modes of driving the H-bridges on motors 
12 - 16.

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
4.0

Please provide any additional information below.
The product currently only supports Enable PWM. This can result in poor control 
when the robot has high inertia. Phase PWM performs much better. Here's a link 
explaining the difference:

I used to use Enable PWM, and my lawnmower robot couldn't stabilize during 
random spins - power gets removed from the motors as it approaches the desired 
position and it swings right past as the motors freewheel with now power 
applied. PhasePWM keeps full power on as you slow it down and it homes right in.

It is recommended to use closed-loop control such as CQEMotorTraj::Move().
