Starting facs for homeworlds...

[Nitram Draw]

Tested the modified shipyard and it causes problems with the AI.
If you give the shipyard the research or mineral mining capacity the AI tries to build it instead of the standard facility on new colonies but they can only build one per planet so their colonies do not grow. I only tested it for about 35 turns so that may not have been a long enough to test. I am not real familiar with how the AI builds on colonies. Maybe a more experianced modder could figure a way around this.
The best I could do without changing the game to much was give the shipyard the ability of a resupply base. This put two yards per homeworld and didn't seem to affect the AI, again the test was not long. Not much of an increase but at least it is sort of logical to have the yard act as a supply base.
