Add developer keys visualization
Well, almost add it- it is currently commented out as I have a few more things I'd like to take care of, namely correcting static files versioning and caching, to ensure this doesn't break things. This is a force-directed graph drawn using D3 as the package treemap already does. We color the dots by "group", e.g. "dev", "tu", or "master", and then outline developer keys in green if they have at least 3 master key signatures, red if they have fewer. Hovering over a circle will show you who's key you are seeing in the visualization. Signed-off-by: Dan McGee <dan@archlinux.org>
