* 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

RouteSet does not raise ActionController::RoutingError when no routes match anymore. Instead, it follows the X-Cascade convention. ShowExceptions checks for X-Cascade so that the routing error page can still be displayed.

ActionCachingTestController rescues from all exceptions. Making sure that all the tests check for valid response. [#4468 state:resolved]

Revert "Add test case which check content type when rendering rjs" partial in html template" rendering rjs in html doesn't make sense, it would just output javascript into the template, no script tag

This reverts commit dc251389.

Rename config.cookie_secret to config.secret_token and pass it as configuration in request.env. This is another step forward removing global configuration.

  ActionDispatch::Request rather than Rack::Request.

* Changed ActionDispatch::Request#method to return a String, to be
  compatible with the Rack::Request superclass.

* Changed ActionDispatch::Request#method to return the original
  method in the case of methodoverride and #request_method not to,
  to be compatible with Rack::Request

Deprecate cookie_verifier_secret in favor of config.cookie_secret allowing signed cookies to work again.

At this point, its entire purpose in the open_session {} case was to
delegate back to the IntegrationTest anyway.
