Change ActiveSupport::Deprecation to class.

ActiveSupport::Deprecation is now a class rather than a module. You can
get instance of ActiveSupport::Deprecation calling #instance method.

  ActiveSupport::Deprecation.instance

But when you need to get new object od ActiveSupport::Deprecation you
need to just call #new.

  @instance = ActiveSupport::Deprecation.new

Since you can create a new object, you can change the version and the
name of the library where the deprecator concerned.

  ActiveSupport::Deprecation.new('2.0', 'MyGem')

If you need use another deprecator instance you can select it in the
options of deprecate method.

  deprecate :method, :deprecator => deprecator_instance

Documentation has been updated.

## Rails 4.0.0 (unreleased) ##
* ActiveSupport::Deprecation is now a class. It is possible to create an instance
of deprecator. Backwards compatibility has been preserved.
You can choose which instance of the deprecator will be used.
deprecate :method_name, :deprecator => deprecator_instance
You can use ActiveSupport::Deprecation in your gem.
require 'active_support/deprecation'
require 'active_support/core_ext/module/deprecation'
class MyGem
def old_method
end
deprecate :old_method => :new_method, :deprecator => deprecator
def new_method
end
def self.deprecator
ActiveSupport::Deprecation.new('2.0', 'MyGem')
end
end
MyGem.new.old_method
DEPRECATION WARNING: old_method is deprecated and will be removed from MyGem 2.0
(use new_method instead). (called from <main> at file.rb:18)
*Piotr Niełacny & Robert Pankowecki*
* `ERB::Util.html_escape` encodes single quote as `#39`. Decimal form has better support in old browsers. *Kalys Osmonov*
* `ActiveSupport::Callbacks`: deprecate monkey patch of object callbacks.

#
# You can use custom deprecator instance

# deprecate :foo, :bar => "warning!", :deprecator => MyLib::Deprecator.new
#
# \Custom deprecators must respond to one method
# [deprecation_warning(deprecated_method_name, message, caller_backtrace)] will be called with the deprecated
# method name, the message it was declared

# Example
# class MyLib::Deprecator
#
# def deprecation_warning(deprecated_method_name, message, caller_backtrace)
# message = "#{method_name} is deprecated and will be removed from MyLibrary | #{message}"
# Kernel.warn message

# When we deprecate method
# class MyLib::Bar
# deprecate :foo => "this is very old method", :deprecator => MyLib.deprecator

# It will build deprecation message and invoke deprecator warning by calling
# MyLib.deprecator.deprecation_warning(:foo, "this is a very old method", caller)
