FtA game engine

[Finnik]

Making a change here: https://github.com/723Studio/OpenXcom_FTA/blob/fta/src/Engine/Options.cpp#L563
(and maybe here?: https://github.com/723Studio/OpenXcom_FTA/blob/fta/src/Engine/Options.cpp#L903)
should be enough.

Thanks for the hint. I made a quite simple and brutal change, as I do not expect any other FTA-compatible master mods to appear any soon =)

I would love to see some UNEXCOM bureau 11 and directorate 17 use your engine fork to have some interesting features that can be used as spy related activites in the game.
