[20479] Bug #644762: Deprecated __new__() call in function_class.py

Patch by Sara Arenson:

Patch to fix the deprecated __new__() call in function_class.py

When you create an object of type ClassFromFunctions (a subclass of object),
you get the following warning:

/opt/gnucash-2.4.0/lib/python2.6/site-packages/gnucash/function_class.py:55:
DeprecationWarning: object.__new__() takes no parameters
  return super(ClassFromFunctions, cls).__new__(cls, *args, **kargs)

As per Python docs (http://docs.python.org/reference/datamodel.html), __new__()
accepts class name and a list of arguments for the object's constructor.  Since
ClassFromFunctions's superclass's constructor has no arguments, we should not
be passing *args and **kargs.
