Simplifying python results code.

Move org-babel-python-table-or-results into the :results value branch
of org-babel-python-evaluate, and get rid of default case (result-type
must always be either output or value). I wonder if the org-babel-trim
s are necessary: they don't seem to be needed in the code for ruby.
