fancyopts: add support for custom multi-arg opts in fancyopts.py

This allows for more complex multi-arg opt logic, such as "--sum 1 --sum 2"
-> 3, "--csv alice,bob --csv charlie" -> ["alice","bob","charlie"].  The
current support for callables is insufficient for this.

This is done by introducing a 'customopt' class which can be extended for
more powerful opts logic.  All existing opt-types are converted to use this
class, simplifying the fancyopts() logic.
