Improved guessCPythonCheckFunction method to produce an AbstractMetaType for known types.

This is in opposition of simply returning a string with a custom type
check. The details are in the docstring in ShibokenGenerator header.

Also added a new modification test and refactored here and there in the
sample binding type system.
