Stellar Manipulation Mods

[Kimball]

Here is the fix. All I did was add Stellar Manipulation back into the techarea.txt file. There are not any components linked to the Stellar Manipulation tech area, as far as I know, but this will prevent any Messages generated by the AI not being able to find Stellar Manipulation in the _AI_research.txt file. Eventually, I will fix all the AI files so that they can have the same stellar manipulation abilities as human players. Once again, I apologize for not finding this sooner.
