Dev chat reminder, issue 28940b4f-8ed6-46d9-8b66-ff93461c467b

This week I mostly worked on Picard, first finishing the "Add new
files" feature, and then fixing a lot issues raised during the
comments: https://github.com/musicbrainz/picard/pull/343

I've also created most parts of the ui, and just need to add the event
handlers now.

In the original ui, plugins which have an update available are shown
in bold http://i.imgur.com/zyxDp3a.jpg

The download ui is shown as a child of the Plugins list

The code is here:

I also improved the script that creates the json data from a folder of
plugins: https://github.com/musicbrainz/picard-website/pull/6
