Changes

* Try and get a few addon developers involved early to give feedback on coverage and quality of the documentation. Target Web Developer Addons since these kind of addons also help to increase use of the beta releases if they are available at beta release time. - '''rey, paul'''

* Set up tracking bugs for the top 50-60 addons to track progress on contacting, updating, and feedback about how things are going with getting compatible. ala https://bugzilla.mozilla.org/showdependencytree.cgi?id=364745&hide_resolved=0 - '''chofmann, rey''' (also, we should make sure we have to do this)
