Subject: Significantly improved internal encoding heuristics and support.

* 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
