Allow veterancy to deliver different bonuses per faction and/or per unit.

Right off the bat this would help diversify the factions and simultaneously tie up the game a bit to the original with distinct faction specialties regarding, speed, armor, firepower, etc.

Detailing the effect per unit would involve combat units, but perhaps also to various utility units such as Harvesters, MRJs, MAD Tank, etc.
