Code review comment for lp:~dobey/ubuntu-printing-app/add-notifier-daemon

I've added a document to the tree to describe how to test it (as testing cups notifications can be a bit weird to do). I would recommend avoiding having the daemon running in unity 7 as it's not meant for it, and meant to replace the printing indicator for unity 8 session only. (The notification service under unity7 creates a GTK+ dialog that has some additional buttons, for the printer error notifications.)

As for the translations, I had set up the po/ dir already in my branch prior to adding it in yours, and I removed what I had to avoid the conflict. At this point, I think it's probably better to fix that in another branch on top of these (perhaps after they land, as I don't want to get into a weird situation where we keep adding conflicts). There's also some improvements that can be taken from my work here, and applied to the rest of the project tree, now that I see you've added more testing there, but I think that cleanup should happen in another branch too at this point.
