[3.1.0.rc1] Plugins inside engines not eager-loaded properly and their
rake tasks ignored

Working with the new support for plugins inside engines in Rails 3.1,
I found that certain things that work for regular plugins don't work
for these new nested plugins. In particular, these methods in
Rails::Engine don't seem to understand that an engine could have
nested plugins:

#load_tasks
#load_generators
#load_console
#eager_load!

A solution which worked out for me is to move the calls to
railties.all { ... } from the overriding methods in Rails::Application
into Rails::Engine.
