Adjust test suite to work with the current version of svntest.

Adjust test suite to work with the current version of svntest.

With this change, the test suite works with all versions of
Subversion, including Subversion >= 1.6.0 (which was broken due to a
change in the output format of "svn proplist -v").  Thus issue #124 is
fixed.

This change relies on r38486 in the Subversion svntest module.  It
changes the svn:external to pull in the HEAD version of svntest; we
can try to track svntest again.

* run-tests.py (Cvs2SvnTestFunction): New class, derived from
  TestCase.  It can be used as a decorator for no-argument test
  functions.

  (Cvs2SvnTestCase.__init__): Rename the "description" parameter to
  "doc".  Pass it to the TestCase constructor.

  (Cvs2SvnTestCase.get_description): Remove method.

  (Cvs2SvnTestCase.get_sandbox_name): New method.

  (Cvs2SvnPropertiesTestCase.run): Accept a sandbox parameter.

  (ignore): Fix the end-of-line characters in the expected property
  values to work with the new svntest output.

  (<rest of file>): Decorate all test functions with
  Cvs2SvnTestFunction).  Accept a sandbox argument to all other test
  cases' run() methods.

  (svntest): Change svn:external to pull in the HEAD version of
  svntest from the Subversion project.
