Ruby version of previous commit.

    Bug fix: I was missing out org-babel-table-or-string with external
    process evaluation (non-session).

    Also, I have renamed org-babel-ruby-table-or-results to org-babel-ruby-table-or-string.

    (the previous commit's message should have read org-babel-python-table-or-results...)
