Enums should not be (badly) emulated with classes in C# but should
use native C# enums instead. Java implementation made an explicit
choice not to use the (more complex) Java enums, but C# enums are
just light-weight syntactic coating over integral types.
Fixes issue #171.

Also made the C# implementation support unsigned types, and
made it more like the Java version.
