Add lite build setup to allow simple deployment of mod builder without using pyinstaller

[xezon]

I would love to get rid of the PyInstaller crap and have it somehow run with just lose python files, then make this repository a submodule in https://github.com/TheSuperHackers/GeneralsGamePatch.

If we can manage that it would be fantastic.

Mod Builder currently is deployed as a PyInstaller build, that is compressed into 7z, then uploaded somewhere and downloaded by a batch script. This is too much maintenance and a burden to maintain because of the frozen python distribution.
