added 3 units

Merchant Donderbuss -a 2 ammo shotgun crew

Hand Mortars

Heavy Muskets

change the scripting a bit and change the pikemen for my donderbuss at the start of the game and added owning a caravel ship for player, so now you have a merchant caravel and a caravel

edit: change the secondary building need by Hand Mortars and Heavy Muskets from armoury to Hunting Lodges
