This reverts commit b3125c89f42968bec6ee0b92ab93e36dbc36d5c3.
* It is not desirable to set `ENV['RAILS_ENV']`; otherwise, it will leak
through to rake tasks such as `rake test` or `rake spec`. See #7175
for more details.
This is an alternative implementation to #7771 thanks to the advice of @spastorino
Rails is a dynamic framework that serves a static index.html by default. One of my first questions ever on IRC was solved by simply deleting my public/index.html file. This file is a source of confusion when starting as it over-rides any set "root" in the routes yet it itself is not listed in the routes. By making the page dynamic by default we can eliminate this confusion.
This PR moves the static index page to an internal controller/route/view similar to `rails/info`. When someone starts a rails server, if no root is defined, this route will take over and the "dynamic" index page from rails/welcome_controller will be rendered. These routes are only added in development. If a developer defines a root in their routes, it automatically takes precedence over this route and will be rendered, with no deleting of files required.
In addition to removing this source of confusion for new devs, we can now use Rails view helpers to build and render this page. While not the primary intent, the added value of "dogfooding" should not be under-estimated.
The prior PR #7771 had push-back since it introduced developer facing files. This PR solves all of the same problems, but does not have any new developer facing files (it actually removes one).

ATP Railties and Actionpack.
Changes:
* `Rails.initialized=` has been removed
* `Rails.initialized?` and `Rails.application.initialized?` are now
* delegating to `MyApp::Application.initialized?`
* Default Encoding.default_internal to UTF-8
* Eliminated the use of file-wide magic comments to coerce code evaluated inside the file
* Read templates as BINARY, use default_external or template-wide magic comments
inside the Template to set the initial encoding
* This means that template handlers in Ruby 1.9 will receive Strings encoded
in default_internal (UTF-8 by default)
* Create a better Exception for encoding issues, and use it when the template
source has bytes that are not compatible with the specified encoding
* Allow template handlers to opt-into handling BINARY. If they do so, they
need to do some of their own manual encoding work
* Added a "Configuration Gotchas" section to the intro Rails Guide instructing
users to use UTF-8 for everything
* Use config.encoding= in Ruby 1.8, and raise if a value that is an invalid
$KCODE value is used
Also:
* Fixed a few tests that were assert() rather than assert_equal() and
were caught by Minitest requiring a String for the message
* Fixed a test where an assert_select was misformed, also caught by
Minitest being more restrictive
* Fixed a test where a Rack response was returning a String rather
than an Enumerable
