[Laszlo-dev] For Review: Change 20080217-bargull-4 Summary: LzState#remove and constraints

[André Bargull]

Developer's Guide :: "Chapter 27. Constraints"

- 2.2. Creating constraints from script
  Needs to be updated to use "applyConstraintMethod" instead of 
"applyConstraint".

 - 6. Circular Constraints
  Doesn't work anymore, because the constraints don't get re-applied 
after the states have been removed.
  Is this a common UI-mechanism, thinking of slider-controls which react 
on each other, but also can be controlled by the user.
