Legio Battlegroup auxiliary reinforcement restrictions can be broken

[MoDLegion]

Auxiliary titans are limited to 1 per maniple in a Legio Battlegroup, but the validation of this rule breaks whenever the allowed 'max' selections becomes -1, as BS treats this as a NULL value. E.g. if you add 2 auxiliary titans of a different type and no maniples, there will be no validation error as both have a max of -1. Any other combination of # of maniples and specific counts of auxiliary titans that result in the calculated max for that specific titan to be -1 will break the validation.

This mostly the fault of BS, I couldn't find another way of implementing these restrictions but if somebody could that would be swell.

This is now fixed as of v9.81.1
