media:title ignored or used for main item title

** What steps will reproduce the problem?

To reproduce, download the attached file and run:

python -m feedparser file:///Path/to/media_title_error.xml

** What is the expected output? What do you see instead?

For example, the attached file has a media:content element, with a media:title 
element inside. This produces this list of entries:

[{
    'media_content': [{'medium': u'image',
                       'url': u'http://example.com/image.jpg'}],
    'title': u'MAIN TITLE',
    'title_detail': {'base': u'file://Path/to/media_title_error.xml',
           'language': None,
           'type': 'text/plain',
           'value': u'MAIN TITLE'}}],

I would expect the title of the media_content element to appear:

[{'media_content': [{'medium': u'image',
                             'url': u'http://example.com/image.jpg'
                             'title': u'MEDIA TITLE'}],
    'title': u'MAIN TITLE',
    'title_detail': {'base': u'file://Path/to/media_title_error.xml',
                               'language': None,
                               'type': 'text/plain',
                               'value': u'MAIN TITLE'}}],

** What version of the product are you using? On what operating system?

I'm using feedparser-5.0.1 on Python 2.6.1 on Mac OS X 10.6.6. I also tried SVN 
HEAD with the same result.

** Please provide any additional information below.

If the parent feed item doesn't have a title element, the media:title content 
appears as the item's title instead. This suggests that this bug is related to 
issue #76:

• media_title_error.xml

Start by running python -m feedparser with the attached media_title_error.xml and inspect how media:title is handled inside media:content. Confirm the expected result: the media item gets its own title while the parent entry keeps MAIN TITLE; also check the reported behavior when the parent has no title.】【。
