Patch Improvements

[Taqwus]

Global tax default: Mostly useful for AE Ermor: the ability to set the default tax rate to '200 and ignore unrest', since the pop is going to die rapidly anyway.

Possible 'extra size in formation' value: Recalling discussions of light infantry formations in Dom2, it seems to be that if there were an additional modifier that added to size -for the sole purpose of determining how full a square is- that +1 could be added to LI or similar irregulars not trained for close-formmation combat. +1 on size-2 human = 2/square instead of 3.
