Actions can now clone() and split off prepare() from call().

  • ActionQueue now separates call phase into clone(), prepare(), and call().
  • ActionQueue's dstor releases Actions in deque.
  • CurrentAction is an index as push_back always invalidates iterator.
  • ActionQueue_t is now a simple vector of ptrs.
  • call() is now non-interactive, (maybe) interactive part is placed in prepare() where dialogs are used to fill parameters.
  • only fully prepared Actions are placed in ActionQueue.
  • ActionQueue obtains action instances from Registry, copies, prepares them, and places them in the queue.
  • Action::clone() gets QueryOptions as param. This lets us either clone without params or really copy the instance.
  • If action is called as COMMAND, params have been filled already.
  • Reactions require a ActionQueue::getLastAction() to actually obtain result of (cloned) Action.
  • FIX: Calculation now has const has...() and getResult().
  • Property mode set to 100644
