EDT-775: In ACTION archetypes, remove the Transitions option from the Pathway Specification. It has never worked and no one has ever found that the transition constraints should be limited more than the standard openEHR state diagram. The partial implementation that was in place also seemed back-to-front with respect to the reference model: the RM specifies the transition that which occurred to arrive in the current state, whereas the user interface was constraining which states could be reached from the current state. For simplicity and to avoid confusion, it's best to remove the existing non-functional implementation.
