Comply to CLS

[thomas-pemsel]

This cast from uint to int is necessary because of the Take operation we use inside the shuffler. This could be a - albeit very theoretical - future problem when we introduce custom minefields since one could define a minecount that's greater than an int.
For now maybe we should throw an ArgumentException in the constructor of the Minefield in case someone tries to generate it with a minecount greater than int.MaxValue?

Add CLSCompliantAttribute and change e.g. uint to int with negative value validation.
Use ArgumentOutOfRangeException

Hopefully dotnet/msbuild#6285 is implemented by then ;)
