Vapi generation: No full namespace for default parameters when based on constant

Submitted by Jan-Jaap van der Geer

Link to original bug (#601461)

Description

Assume this vapi:

namespace Test
{
  public const int ConstInt;
}

and this class:

using Test;

public class TestClass
{
  public void TestMethod(int someInt = ConstInt)
  {
  }
  public static void main()
  {
  }
}

Generating a vapi of this class gives:

public void TestMethod (int someInt = ConstInt);

"ConstInt" makes no sense in this context, it should have been "Test.ConstInt" (or some using-statements).
