[Nitro] Fixes in repo

[Jonathan Buch]

Hi,

> fixes for all reported problems are already in the Repo.

Please look at taggable, add this to the top of the testcase below the article.

  class Second
    attr_accessor :haha, String
    is Taggable
  end

  $og1.manage_classes(Article, Tag, Second)

By adding this second class and running the testcase again, you will see 
that it always uses the second class gets the tags.. very weird.
Can't follow this further right now, fixing Oxy to get it out to the
public as soon as possible.
