For bitbucket issue #2, tweak the admin settings for the Post model to reduce slow queries. Define our own queryset() method so we can control the select_related(), and not have it cascade from post to topics to forums to categories. Removed 'topic' from list_display because MySQL still sucked with 2 inner joins. Now it seems to be tolerable with only one join to User.

    {
        "pk": 1, 
        "model": "oembed.provider", 
        "fields": {
            "api_endpoint": "http://www.youtube.com/oembed", 
            "name": "YouTube", 
            "url_regex": "^http://www\\.youtube\\.com/watch\\?v=\\S+$", 
            "format": 0
        }
    }
