Worldbuilder improvements

[ben132]

I stated this in the Discord but I thought I could start a discussion here.

The main suggestion I have is to add a "Robust" Scripting System to the worldbuilder, similar to Warcraft 3, allow for the creation of custom game modes for example.

Also the ability to "import" different game mechanics into said engine, games like Blizzard games and other Command and Conquer games, or BFME etc.
