Introduce config.action_mailer.default_from=

Allows to easily set :from, :replay_to, etc. options in
config/application.rb using simple syntax:

  config.action_mailer.default_options = {from:"no-replay@example.org"}

This was not possible using #default method because

  config.action_mailer.default(from: "no-replay@example.org")

is interpreated as reader method and just returns nil.
It would not call ActionMailer::Base.default method. The only
way of calling this method from config/application.rb was to use
the direct syntax which looks ugly in my opinion:

  config.assets.enabled = false
  config.assets.version = '1.0'
  config.encoding = "utf-8"
  config.action_mailer.default_url_options= {
    host:"example.org",
    protocol:"https"
  }
  ActionMailer::Base.default(from: "no-replay@example.org")
