Ignored enum fixes.

C#/Java - Enums which have been ignored via %ignore and are subsequently
used are handled slightly differently. Type wrapper classes are now generated
which are effectively a wrapper of an empty enum. Previously in Java uncompilable
code was generated and in C# an int was used.
