1.9.3 - Minor compatibility fixes with functools.partial

• @wraps can now be used to wrap a functools.partial. Fixed #57

• create_function now correctly reuses information from the partialized function if a functools.partial is used as the implementation.

• create_function now raises a more explicit error when no func_name can be found.

• makefun.partial now generates a signature that is more consistent with functools.partial. Fixes #58
