Patch to Bio/Seq.py and Bio/Alphabet/__init__.py

Implements upper/lower methods in the Seq object, handling the alphabet case
conversion in the Alphabet object using (private) upper/lower methods.  This
could be extended for the IUPAC alphabets if we add lower case variants to
those (see Bug 2532).

This works for the evil example in comment 3 where the case of any extra
characters from an AlphabetEncoder should also be changed.
