[PATCH] Fix ob-clojure handling source block variable's value is a org-mode table or list

[Christopher M. Miles]

I bellowing example:

#+begin_src org
,#+NAME: ob-clojure-table-test
| a | b | c |
|---+---+---|
| 1 | 2 | 3 |

,#+NAME: ob-clojure-table-test-2
| a | b | c |
|---+---+---|
| 1 | 2 | 3 |

,#+begin_src clojure :var kk=ob-clojure-table-test :var 
kk2=ob-clojure-table-test-2 :results output
(println kk2)
(println kk)
,#+end_src

#+end_src

Without this patch, it will report error "class java.lang.ClassCastException" 
from CIDER.

This patch added if condition to handle this table, list type data.
