Generate namespaced interactors/organizers in the right directory

[ersatzryan]

[Fixes #5]

rails g interactor foo/bar should generate app/interactors/foo/bar.rb

currently this generates

class Foo::Bar
  include Interactor

  def call
  end
end

which is less than ideal, but follows how Rails does it

Coverage remained the same when pulling 166d5e9 on rg-better-generators into e144128 on master.

This test should be generating an organizer but it looks like a copy/paste of the interactor test.

<<-EOF.sub(/^\s{10}/, "") (or whatever the right number of spaces is) and then indent the code below so it fits better.

[laserlemon]

Yeah it looks like junk in the test but it also makes it clear exactly what the expected output is without concern over indentation. Active Support gives you String#strip_heredoc but it's not available to us here. I'm comfortable leaving this as is.
