`internal` Types With Parameters Defined With `internal` Types Cause Errors

[JasonBock]

To Reproduce

Create this code in an assembly targeted by a test assembly that's using Rocks:

[assembly: InternalsVisibleTo("RocksInternals.Tests")]

internal interface IDoStuff
{
  void Do(DataStuff dataStuff);
}

If DataStuff is public, this works in the test assembly:

[assembly: Rock(typeof(IDoStuff), BuildType.Create)]

But if DataStuff is internal, the following diagnostics occur:

The type IDoStuff has inaccessible abstract members and cannot be mocked
The type IDoStuff has no members that can be overriden

Also, "overriden" is misspelled, it should be "overridden".
