Currently when you submit an image all that happens is it shows up
on the mainpage as a thumbnail. Boring! We should be able to view
those images on their own page.

If I upload the media entry of "A Walk in the Park" which has the
ID of 4d8e5b0048b1520586000000, I should be able to view that at:

[http://mediagoblin.example.org/\ :sub:`cwebber/m/d8e5b0048b1520586000000/](http://mediagoblin.example.org/`\ cwebber/m/d8e5b0048b1520586000000/)

(Eventually I'll also want to be able to view it by its prettier
slugified URL:

[http://mediagoblin.example.org/\ :sub:`cwebber/m/a-walk-in-the-park/](http://mediagoblin.example.org/`\ cwebber/m/a-walk-in-the-park/)

... but that's waiting on
`http://bugs.foocorp.net/issues/306 <http://bugs.foocorp.net/issues/306>`_
)

This URL should have the following things:


-  The image, fully sized (we don't have scaled down versions
   implemented yet besides the thumbnail, so that's fine)
-  The author's name
-  When it was uploaded
-  The title
-  The description

Mockup:

Don't worry about the comments for now though.

In addition, the thumbs currently on the main page should link to
this URL.

Comments to MediaEntry objects should be possible

I think we don't need to do complicated threading for now. Just
comments which are paginated. Restricting to users registered on
that site for now is good enough. We'll want more than that
eventually, but for now it's okay.


-  Just simple flat comments, no threading (yet)
-  Just comments by logged in, active users
-  pagination of comments! Sorted by comment time, obviously.
-  Don't embed the comments, make the comments link back to the
   MediaEntries via their ObjectIds

That's it :)

Similar to
`http://bugs.foocorp.net/issues/362#note-2 <http://bugs.foocorp.net/issues/362#note-2>`_
we should have descriptions be in markdown, and then we should
prerender them and display that prerendered niceness.

::

    >>> entry['description'] = 'I am *soooo* hungry!'
    >>> entry.render_body()
    >>> entry['description_rendered']
    u'<p>I am <em>soooo</em> hungry!</p>'
    >>> entry.save()
