get_comment_app calls __import__ with strings instead of dictionaries for 2nd and 3rd arguments

[Jacob Fenwick]

When the comment_tests test is run under jython, I get this error:

======================================================================
ERROR: testGetCommentApp (regressiontests.comment_tests.tests.app_api_tests.CommentAppAPITests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/Users/jacob/projects/djython/django-1.0.X/tests/regressiontests/comment_tests/tests/app_api_tests.py", line 11, in testGetCommentApp
    self.assertEqual(comments.get_comment_app(), comments)
  File "/Users/jacob/projects/djython/django-1.0.X/django/contrib/comments/__init__.py", line 20, in get_comment_app
    package = __import__(comments_app, '', '', [''])
  File "/Users/jacob/projects/djython/django-1.0.X/django/contrib/comments/__init__.py", line 20, in get_comment_app
    package = __import__(comments_app, '', '', [''])
TypeError: str indices must be integers

The problem is that the import function is taking a string for the second and third arguments when the parameters should be dictionaries. Python seems to coerce the strings into the correct format, but jython does not.

Here is the patch, which should be applied to all version of django:

svn diff init.py

Did the svn diff from the trunk instead of on the file (oops)
