fix behavior when after_initialize is defined and a block is passed to Base.create

Cache key was incorrectly using timezone-dependent record#updated_at when it should be using a timezone-independent value to generate the cache key

Minor refactoring to cache_key timezone test

Closes #2059

Adds a test to validate the format of the cache_key for nil and present updated_at values

Correctly handles updated_at == nil

Refactor Active Record test connection setup. Please see the RUNNING_UNIT_TESTS file for details, but essentially you can now configure things in test/config.yml. You can also run tests directly via the command line, e.g. ruby path/to/test.rb (no rake needed, uses default db connection from test/config.yml). This will help us fix the CI by enabling us to isolate the different Rails versions to different databases.

ActiveSupport::Dependencies now raises NameError if it finds an existing
constant in load_missing_constant. This better reflects the nature of
the error which is usually caused by calling constantize on a nested constant.

Closes #1423

Add ActiveRecord::attribute_names to retrieve a list of attribute names. This method will also return an empty array on an abstract class or a model that the table doesn't exists.

deprecated the use of the guard_protected_attributes argument with attributes= in AR in favor of assign_attributes(attrs, :without_protection => true)

Added assign_attributes to Active Record which accepts a mass-assignment security scope using the :as option, while also allowing mass-assignment security to be bypassed using :with_protected

The identity map cache prevents us from seeing the DB formatted strings.

Evaluate default scopes at the last possible moment in order to avoid problems with default scopes getting included into other scopes and then being unable to remove the default part via unscoped.

Deprecated support for passing hashes and relations to default_scope, in favour of defining a 'default_scope' class method in the model. See the CHANGELOG for more details.
