Since #5581 added support for resources with custom params we should
not assume that it is :id when using shallow resource routing.

The Mapper looks for a :id constraint in the scope to see whether it
should apply a constraint for nested resources. Since #5581 added support
for resource params other than :id, we need to check for a constraint on
the parent resource's param name and not assume it's :id.

This allows us to do:

In your configuration:
Rails.queue[:image_queue] = SomeQueue.new
Rails.queue[:mail_queue]  = SomeQueue.new

In your app code:
Rails.queue[:mail_queue].push MailJob.new

Both jobs pushed to the same default queue
Rails.queue.push DefaultJob.new
Rails.queue[:default].push DefaultJob.new

Log query plan when we use count_by_sql method.

Lets stick with a symbol in join table name, it was removed in
993e1643 and broke the build.

Add fkey attributes to `join_table` migration generator

This reverts commit c08f30ff, reversing
changes made to e243a8a3.

revert Default timestamps to non-null

Commit 3dbedd28 added NOT NULL constraints to timestamps.
Commit fcef7289 started to revert this, but was incomplete.
With this commit, 3dbedd28 should be fully reverted and
timestamps will no longer default to NOT NULL.

Remove `:confirm` in favor of `:data => { :confirm => 'Text' }` option

This applies to the following helpers:
`button_to`
`button_tag`
`image_submit_tag`
`link_to`
`submit_tag`

Don't use default separator in tagged logger

When the default separator is set logger will create incorrect output

add lazy look up in abstract controller's translate method

Add indexes to create_join_table method

Add additional formats to lookup context

AR::Integration must be included after AM::Conversion

Integration's definition of #to_param must override
Conversion's. Otherwise, there is a regression from
3.1 in the behavior of a non-persisted AR::Base instance
which nevertheless has an id.

For instance, running

    rails g migration CreateMediaJoinTable artists musics:uniq

will create a migration with

    create_join_table :artists, :musics do |t|
      # t.index [:artist_id, :music_id]
      t.index [:music_id, :artist_id], unique: true
    end

Optional segments with a root scope need to have the leading slash
outside of the parentheses, otherwise the generated url will be empty.
However if the route has non-optional elements then the leading slash
needs to remain inside the parentheses otherwise the generated url
will have two leading slashes, e.g:

Blog::Application.routes.draw do
  get '/(:category)', :to => 'posts#index', :as => :root
  get '/(:category)/author/:name', :to => 'posts#author', :as => :author
end

$ rake routes
  root GET /(:category)(.:format)              posts#index
author GET (/:category)/author/:name(.:format) posts#author

This change adds support for optional segments that contain a slash,
allowing support for urls like /page/2 for the root path, e.g:

Blog::Application.routes.draw do
  get '/(page/:page)', :to => 'posts#index', :as => :root
end

$ rake routes
root GET /(page/:page)(.:format) posts#index
