This reverts commit 86c640a1, reversing
changes made to a0c2cfdc.

Remove unused test code.

ActionController::RoutingError are raised in router execution time and can not be
rescued in a controller.

remove autoload for OrderedHash, usages removed already

Update Gemfile to use 'debugger' instead of unmaintained 'ruby-debug19'

Make log_level explicit in production.rb template

The 'production' environment name is currently checked for setting up
the default log_level to 'info' but that won't work if the environment
is copied to staging.rb, for instance. Better to have it explicitly set.

fixed broken build after multi_json upgrade

Multi_json also upgraded.

fix scaffold_generator_test.rb
