Added a unit test which consists ofa python class inheriting from a C# class which has a virtual generic method. In this version, this causes a InvalidProgramException to be thrown during class creation.

Previously an exception was thrown during class creation if the python class inherited from a class with a virtual generic method.This has been fixed by ignoring generic methods when creating overloads in the generated class. Note, this means that generic virtual methods cannot be overridden in python code.

- Changed the behavior so that a .NET is always created when the base type is also a .NET type.

- Added shortened Attribute aliases which just generates tuples.- More general CLR base class support - creating a class instance from C# is now more similar to creating one from python.- Added attribute decorator to clr.py.- Added testing for the various possibilities

- Fixed search bug in AssocAttribute- Added testing

…attribute.

… inside a .NET module.

There are small typos in:- pythonnet/__init__.py- tests/test_import.pyFixes:- Should read `splitted` rather than `splited`.- Should read `loaded` rather than `laoded`.Signed-off-by: Tim Gates <tim.gates@iress.com>

Added support for specifying attributes on property-methods (eg. get/set attributes).
