AI (Economy): AI player creates too many bows

[PaweX]

The AI player sometimes begins to create a lot of bows and not many swords or spears. Therefore it results in having an army of bowmen:

Sometimes AI player doesn't create any bows at all for a long time.

There should be a code preventing it to happen so there is always a minimum percent of bows (e.g. 5%) or other weapons that are being made. When it comes to swords and spears, they should never go below some percent like below 30% or 40% (together spears and swords comparing with bows).

Edited: I forgot to mention that in my case there was no swordsman or spearman so that blue army could not capture any building. Anyway AI needs army system to create multiple armies as it is in S3 and S4 - some to protect colony some to attack - then we can check if army have enough swordsmen or spearmen.
