Priority change action should also apply to recipes

[rensink]

Rule priorities can be changed in two ways: by changing the rule properties in the properties panel (SetPriorityAction), or by shifting the priorities in the rule tree (ShiftPriorityAction). The second method does not work for selected recipes, though, mainly because the selected recipes are not reflected in the SimulatorModel.

Recipe priorities can only be changed by manually changing the control program.

CtrlLoader.changePriority (untested!) does the work of changing the control programs so that new priorities are reflected, but to invoke it, SimulatorModel should be adapted to include the selected recipes.

Having an explicit set of selected actions (rules + recipes) would also allow getting rid of some strange (erroneous) selection behaviour: if you select a recipe, a rule also gets selected because currently the assumption is that every resource must be selected.
