Make.WordPress.org/core is scaling terribly

This is a more generalized follow-up to #69.

It takes 16 seconds to trigger the window load event. Like, woah. 250 HTTP requests on the homepage, out of which about 60% are gravatars.

Yes, this is just insane, especially considering that it's the comments triggering most of this, and they're even hidden by default on load.

A possible approach might be:

Using the ​lazy load plugin to lazy load all the gravatars. I think it takes into account not yet displayed images (hidden by "Toggle comments" link), we can trigger the plugin when you click the link.

If you want I can try to make a proof of concept patch.

It may be better to just get O2 working -- I believe that it handles delayed loading of gravatars to an extent -- they normally populate as a dummy gravatar then shortly thereafter replace with the real ones.

I've been spending some off hours over the past week polishing up some of the coarser bits of the codebase.

We switched to o2. Whee!
