prevent error in Octave process, add tests, update test docs 
* lisp/ob-octave.el (org-babel-execute:octave):

  -Ensure that the special Octave variable `ans' is bound when
  GFX-FILE is non-nil.  The glue code in
  ORG-BABEL-OCTAVE-WRAPPER-METHOD causes Octave to exit with a
  non-zero exit code when `ans' is not bound.

  -Change format control string to %S from %s.  Ensure the graphics
  filename is quoted.  If it is not, Octave may create a mis-named
  file or fail entirely.

* testing/examples/ob-octave-test.org:

  Update the Graphical tests section:
  -put in the correct headers;
  -add a remark about where to find each test.

* testing/lisp/test-ob-octave.el:

  Add the three tests ob-octave/graphics-file,
  ob-octave/graphics-file-session and ob-octave/graphics-file-space.

  -ob-octave/graphics-file: The first test verifies that the first bug
  identified above is fixed; it also verifies that graphics file
  creation works correctly for scripting.

  -ob-octave/graphics-file-session: The second test verifies graphics
  file creation works correctly for sessions.  The Octave command
  `crash_dumps_octave_core(0)' is included to prevent the creation of
  a core file (`octave-workspace').

  -ob-octave/graphics-file-space: The third test verifies that a
  graphics filename with a space in it is created correctly.

Thanks to Ihor Radchenko for helpful feedback.
