Nested class improvements - Fixed inconsistency in handling C++ nested classes - sometimes they were treated as forward declarations, other times as if C nested struct was parsed. Added the nestedworkaround feature for C++ nested class handling. Document improved nested class handling. Numerous C and C++ nested struct/class/union test cases added.

Version 1.3.41 (in progress)
============================
2009-11-11: wsfulton
Added the nestedworkaround feature as a way to use the full functionality of a nested class
(C++ mode only). It removes the nested class from SWIG's type information so it is as if SWIG
had never parsed the nested class. The documented nested class workarounds using a global
fake class stopped working when SWIG treated the nested class as an opaque pointer, and
this feature reverts this behaviour. The documentation has been updated with details of how
to use and implement it, see the "Nested classes" section in SWIGPlus.html.

There were a number of C++ cases where nested classes/structs/unions were being handled
as if C code was being parsed which would oftentimes lead to uncompileable code as an
attempt was made to wrap the nested structs like it is documented for C code. Now all
nested structs/classes/unions are ignored in C++ mode, as was always documented. However,
there is an improvement as usage of nested structs/classes/unions is now always treated
as an opaque type by default, resulting in generated code that should always compile.

Fix inconsistency for nested structs/unions/classes. Uncompileable code was being

behaviour the same as an inner class. (C++ code), eg:
