Utilize select_related() for user & user profiles. This commit also removes the caching of the avatar URL in the avatar template tag. This is because we are now using select_related, so we already have the profile & avatar when we get to the tag. Thus we don't need to waste time querying the cache. Removed an apparently unused member map template as well.
