Specify type of singular assication during serialization

Due to a change in builder, nil values and empty strings now generates
closed tags, so instead of this:
<pseudonyms nil=\"true\"></pseudonyms>
It generates this:
<pseudonyms nil=\"true\"/>
Document this change in Rails so that people can track it down easily if
necessary.

At the end of initialize_dup was added the call to super if it exists,
so it also works with 1.8.7 where initialize_dup doesn't exist.
This issu was introduced with the pull request #6324
Since ActiveModel::Errors instance keeps all error messages as hash
we should duplicate this object as well.
Previously ActiveModel::Errors was a subclass of ActiveSupport::OrderedHash,
which results in different behavior on dup, this may result in regression for
people relying on it.
Because Rails 3.2 stills supports Ruby 1.8.7 in order to properly fix this
regression we need to backport #initialize_dup.
Without that patch when using ActiveModel::AttributeMethods
in a class that does not respond to `attributes` method,
stack level too deep error will be raised on non existing
method. While documentation is clear that you need to define
`attributes` method in order to use AttributeMethods module,
`stack level too deep` is rather obscure and hard to debug,
therefore we should try to not break `method_missing` if
someone forgets about defining `attributes`.
Nested I18n namespace lookup under activerecord.models is deprecated now (c19bd4f).
But when a model uses accepts_nested_attributes_for, its Errors object can have
an attribute name with "addresses.street" style. In this case, the dots should be
substituted with slashes so that we can provide the translation under the
"activemodel.attributes.person.addresses/street" key.
This implements the ActiveModel::Serializer object. Includes code, tests, generators and guides.
From José and Yehuda with love.

The following constants were renamed:
ActiveModel::Serialization => ActiveModel::Serializable
ActiveModel::Serializers::JSON => ActiveModel::Serializable::JSON
ActiveModel::Serializers::Xml => ActiveModel::Serializable::XML
The main motivation for such a change is that `ActiveModel::Serializers::JSON`
was not actually a serializer, but a module that when included allows the target to be serializable to JSON.
With such changes, we were able to clean up the namespace to add true serializers as the ArraySerializer.
