Upgraded to Rails 2.3.4 (#3597)

* Ran the Rails upgrade
* Upgraded to Rails Engines 2.3.2
* Added a plugin to let Engines override application views.
* Converted tests to use the new classes:
** ActionController::TestCase for functional
** ActiveSupport::TestCase for units
* Converted ActiveRecord::Error message to a string.
* ActiveRecord grouping returns an ordered hash which doesn't have #sort!
* Updated the I18n storage_units format.
* Added some default initializers from a fresh rails app
* Changed the order of check_box_tags and hidden_field_tags.  The hidden tag
  needs to appear first in Rails 2.3, otherwise it will override any value in
  the check_box_tag.
* Removed the custom handler for when the cookie store is tampered with.
  Rails 2.3 removed the TamperedWithCookie exception and instead Rails will not
  load the data from it when it's been tampered with (e.g. no user login).
* Fixed mail layouts, 2.3 has problems with implicit multipart emails that
  use layouts.  Also removed some custom Redmine mailer code.
* Fixed a bug that occurred in tests where the "required" span tag would be
  added to the :field_status translation.  This resulted in an email string of:

    <li>Status<span class="required"> *</span><span class="required"> *</span>

  Instead of:

    <li>Status: New</li>
