[ckan-dev] git move

[David Read]

The plan is to do the bulk of the migrations first thing tomorrow, so
that it is in time for the DGU packaging.

Here's the list of repos:
https://docs.google.com/spreadsheet/ccc?key=0AvCDqUH8jVN8dGNVNEpXLWk3UTlJZXhFMjBPbXVtRmc
(& I've given edit permission to all the team members - ping me if I
happened to forget you)

James, John, Adria & David (and anyone else able to help), please do
put your name against a bunch of these to do the migrations. I've
taken on all the DGU repos so that I can get buildbot working straight
away (unless any one thinks there might be an issue with that?)

@Rufus in particular, it would be good if you could run through the
list to say what the status of many of these are - it would be good to
mark repos that are deprecated and not worth moving.

Dave
