Raise a RecordNotFound if an ID in nested attributes is given but doesn't return a record. [#2415 state:resolved]

Cleanup some code in nested_attributes.rb, autosave_association.rb, and associations.rb with AssociationReflection#collection_association?

Also cache the result value.

Add an :update_only option to accepts_nested_attributes_for for to-one associations. [#2563 state:resolved]

This makes sure that, in a HABTM association, only one join record is craeted.

This way we don't define all the validation methods for all associations by

Add a :limit option to specify the maximum number of records that can be processed by accepts_nested_attributes_for

Break up DependencyModule's dual function of providing a "depend_on" DSL and "included" block DSL into separate modules. But, unify both approaches under AS::Concern.

Allow you to pass :all_blank to :reject_if option to automatically create a Proc that will reject any record with blank attributes.

Changed API of NestedAttributes to take an array, or hash with index keys, of hashes that have the id on the inside of the attributes hash and updated the FormBuilder to produce such hashes. Also fixed NestedAttributes with composite ids.
