build 986 (WIP): common core:
- addition of a new code unit to put all common core related code in it.
- removed the hardcoded tech level cap for non-player factions, since it's defined into a function now.
- for the final process of a new game, the non-player factions are initialized before the player's faction. It's a requirement for the common core rules.
- a function is added to determine the tech level cap of a research domain of a non-player faction.
Credits Addition:
- Max Hornig is added in the code/design subsection for his translation contributions for the English part.
