Revert "Added ActiveRecord::Base#last_modified to work with the new fresh_when/stale? conditional get methods from Action Pack"

Needless indirection with no added value.

This reverts commit 535853e8.

Added ActiveRecord::Base#last_modified to work with the new fresh_when/stale? conditional get methods from Action Pack

Log 'Filter chain halted as CALLBACKNAME rendered or redirected' every time a before callback halts.

You can provide a namespace for your form to ensure uniqueness of id attributes on form elements.
The namespace attribute will be prefixed with underscore on the generate HTML id

A test case to ensure that AC::Metal#response_body= always wraps the given value in an Array in both Ruby 1.8 and 1.9 (refs #3581)

This reverts commit 10773f94.

This test is affected by a bug in Ruby 1.9.3p0 and trunk:
http://redmine.ruby-lang.org/issues/5564

Given we cannot fix it for ourselves, it is better to skip for now so
that we will easily see if further failures are introduced.

Jon Leighton is monitoring the bug report and will revert this when a
suitable solution is found (either a new Ruby release or a generic
workaround).

If you are using 1.9.3 in your app and have templates that are not in
UTF-8, you should add a workaround early on in the boot process. For
example, if your templates are Shift_JIS encoded, then add the
following in an initializer:

Encoding::Converter.new('Shift_JIS', 'UTF-8')

f.number_field generates <input type="number", size="30"../> which is
invalid HTML5. See: http://dev.w3.org/html5/spec/Overview.html#number-state
