[WIP] Make it possible to edit app status in the lookup tool (bug 1013472)

https://bugzilla.mozilla.org/show_bug.cgi?id=1013472

WIP, I need to make it work for versions as well.
I think there is a better way, I'll look into that. We still haven't cleaned up the constants though, so maybe that's why I used that, I don't remember :)
