support model-servo for movable laser instead of stepper motor

[pointhi]

I don't know if the movable laser is already full suported, but probably it would be a good idea to support model-servos optional to stepper motors.

Advantages:

1.) Servomotors working with absolute positions, stepper-motors only with relative positions
2.) Servomotors are cheaper
3.) Servomotors are repositioning automatically
4.) Servomotors need less power

That's a good suggestion, i already thought about that.
But this brach is deprecated. A first version of the new offical software will be released soon.
You will find further information soon at: http://hci.rwth-aachen.de/fabscanpi

Probably, I could create the required code-changes, as long as laser support is already implemented (I don't know if the lasermotor support is only for develop-purpose, or already working code).
