Build 26362105

changes to opentest branch only.

added ability for promises to use effects from shared effects lists, either the same list used by multiple promises can be written once then used by many, or also one promise can swap out different effects.
made the create_promise effect allow picking effects either with existing effects by setting extra to null, or picking one specific effectslist, or picking prng from many effectslists by having more than one entry in extra.
added new building, the enforcer precinct. this is a small unit (20 men versus pdf army 100 men) that cannot increase in size, doesn't spawn in during generation (so you have to build them yourself), has no controlling faction, and the unit is always loyal to the governor.
added new building specialEffect pdf_loyal, which means it will only make one pdf unit which belongs to the loyalists if no faction controls the site or to whichever faction controls the site if one does.
updated production sites controller changing to change unit faction if controller is changed and site has specialEffect pdf_loyal.
