Introduce generic descriptions instead of using "civilization"

[mbergen]

See also #89

Refer to "civilization or option" where needed, speak of "decide on a pick/ban/steal" instead of "pick a civilization"

I've also looked at the german localization, but until now didn't come up with a good generic phrasing An option would be

Wähle eine Zivilisation Triff eine Wahl

but that gets hard when its

Stiehl eine Zivilisation

maybe

Stiehl eine Wahl des Gegners

could be used altough it gets longer and longer with the other descriptions.

Thanks a lot! :yellow_heart: I'll contact the maintainers of the other languages and we'll see if that can/should be implemented there as well.
