Spear Changes in 1.3

[Red Harvest]

They should be tough frontally vs swords, but maybe some spear units such as germanic spearmen shouldn't have phalanx ability.

I was going to give them short_pike again, but that doesn't seem to work quite right in 1.3.

However, they need to have a knife/sword added for secondary anyway. During 1 vs 1 tests they raise pikes, and punch at the player's men with their fist containing a vertical pike. Plus it would probably weaken them in melee anyway if they had another weapon. I gave them a 5 with a knife/sword.
