An idea for AI ship weapons

[Master Belisarius]

The work around that I did to fix this problem, is having different attack ship designs.
For example, look the Aquilaeian attack ships: they will use DUC cannons until research BC. When the AI research BC, start to use ships with Acid Globulae IV (this avoid the problem to have ships with useless weapons like Acid Globulae I and II).
