Where is it possible to see the list of all available content_types for the message_handler decorator? There's some list in https://github.com/eternnoir/pyTelegramBotAPI#types, but it seems to be incomplete because it doesn't contain at least animation type.

Also it will be convenient to have a simple option to specify all content_types, not only by specifying a big list of all possibile strings.
