Title: Changed factory_girl_rails initializers would allow some (mountable) engines to advertise its own factory definions to be used in a target project

When a (mountable) engine defines models and factories to test the models, sometimes it is convenient to use this factories
from a project which depends on the engine.

But current factory_girl_rail initialization processes do not allow to do so without hacks.
(after_initializer resets all FactoryGirl.definition_file_paths to defaults with = [paths])

When this change introduces the engine can advertise some factories in an its own railtie, i.e.:

module ModelCore
class Engine < Rails::Engine

initializer "doc_store.factories", :after => "factory_girl.set_factory_paths" do
FactoryGirl.definition_file_paths << File.expand_path('../../../spec/factories', __FILE__)
end
end
end
