Remove duplicate tools from Generals

[xezon]

We can remove tools from Generals that are identical to to tools from Zero Hour.

Best if they also have zero dependencies to GameEngine, because then they are not tied to the Generals game code. Unclear if we can already delete tools that are dependent on GameEngine, because that could mean that if Zero Hour code advances but Generals code does not, that a particular Zero Hour tool is then incompatible with the Generals GameEngine.

This is solved. Identical tools were unified to Core.
