Allow for nested attributes for audit

[mguymon]

Allow for nested attributes for an audit. Since the trailing hash is expected to the options, maybe by passing in a block? Something along the lines of:

audit :before_create => :create_audit_callback do 
  audit_attr :name, :arg, :lumox
  audit_attr :user, [:name, :login_at]
  audit_attr :notifications, { :messages => [:title, :sender] }
  audit_attr :cart, { :items => { :inventory => :price } }
end

1. audit_attr :name, :arg, :lumox - Would allow attributes for the model to be added by array
2. audit_attr :user, [:name, :login_at] - Would allow the user attribute to specify what attributes should be serialized by array
3. audit_attr :notifications, { :messages => [:title, :sender] } - Would allow the nested attribute (:messages) to specify what should be serialized.
4. audit_attr :cart, { :items => { :inventory => :price } } - Would allow to specify attributes as an array or single symbol (:inventory)
