increase Fortress recruitment slots to 4; increase Citadel recruitment slots to 5

The higher level agent Guild buildings do not appear to have their triggers functioning correctly. An Assassins HQ for instance will give an assassin trained in any city +2 to skill, however it will not also give the local +1 bonus that a 1st level guild building does. Thus, counter-intuitively, better spies, etc are produced in the lower level city. It appears the 'greater than or equal to' sign is not working properly...

Duplicate the 1st level trigger, and tie the duplicates to the 2nd and 3rd level agent guild buildings
Those fixes would be nice if you actually detailed which file these are in. Otherwise I take it you only meant them as suggestions but don't actually know how to do it.
