Changed the way units upgrade:
It will take 3 turns until unit is finished upgrading
The XP cap is changed to soft cap, but lowered to 4xp / era.
so xp is cap * era plus half above the cap * era.
changed the Militia units. They now basically works like Snipers, meaning they got invisible and AttackAI instead of defenseAI, as I thought it was weird they "ran home" after being spawned by a city capture. Now they work a bit like partisans/resistance/terrorists which was their intended purpose.
The MAXUPT is now based on Era. STARTUP is basenumber (altGlobalDefines.xml)
so... in neolithic the maxupt is now 3 (STARTUP) and increases by 3 per era (MAXUPT)
Neo = 3 , Anc = 6, Cla = 9, Med = 12, Ren = 15, Ind = 18, Mod = 21, Tra = 24, Fut = 27
Changed the Limited Combat Rounds so it withdraws as before, though if successful withdraw the attacker gets XP, but if unsuccessful the defender gets an extra attackround and XP.
