Group C documentation by "fresh" methods

I'm not really sure whether it's better to group novel or fresh methods.
Doing it this way fixes at least the following problems:

* Implementations of abstract methods show up correctly and more
  prominently.
* The statement "Methods inherited from {subclass}" is now correct.
  Before, it should have said "Methods novel in {subclass}".

What bothers me is that methods show up in "vtable" order. Keeping the
original order from the .cfh file would probably be the best solution
but this information is lost in S_bequeath_methods.
