Title: unable to load listen with ActiveSupport 4.0.0-beta1

On ActiveSupport 4.0 environment, Listen isn't work correctly.
I think that reasons is below.

Listen::Adapter.load_dependency is conflicted with ActiveSupport::Dependencies::Loadable.load_dependency.

I renamed Adapter.load_dependency to load_dependent_adapter, and it seems work fine.
