Fixed

• AutoCAD and Civil 3D list the commands of a DLL that has WPF views. Before, such a DLL showed no commands.
• A type or method whose references cannot be resolved no longer hides the other commands of the DLL. It is skipped,
  and the host log names it.
• An AutoCAD command declared with a group, such as [CommandMethod("GROUP", "NAME", CommandFlags.Modal)], shows its
  command name instead of the group name.
