*   Allow the on_rotation proc used when decrypting/verifying a message to be
    be passed at the constructor level.

    Before:

	crypt = ActiveSupport::MessageEncryptor.new('long_secret')
	crypt.decrypt_and_verify(encrypted_message, on_rotation: proc { ... })
	crypt.decrypt_and_verify(another_encrypted_message, on_rotation: proc { ... })

    After:

	crypt = ActiveSupport::MessageEncryptor.new('long_secret', on_rotation: proc { ... })
	crypt.decrypt_and_verify(encrypted_message)
	crypt.decrypt_and_verify(another_encrypted_message)

*   `delegate_missing_to` would raise a `DelegationError` if the object
    delegated to was `nil`. Now the `allow_nil` option has been added to enable
    the user to specify they want `nil` returned in this case.

    *Matthew Tanous*

*   `truncate` would return the original string if it was too short to be truncated
    and a frozen string if it were long enough to be truncated. Now truncate will
    consistently return an unfrozen string regardless. This behavior is consistent
    with `gsub` and `strip`.

    Before:

        'foobar'.truncate(5).frozen?
        # => true
        'foobar'.truncate(6).frozen?
        # => false

    After:

        'foobar'.truncate(5).frozen?
        # => false
        'foobar'.truncate(6).frozen?
        # => false

    *Jordan Thomas*
