About custom filters, the [Wiki](https://github.com/python-telegram-bot/python-telegram-bot/wiki/Extensions-%E2%80%93-Advanced-Filters#custom-filters) says that the `filter` method accepts a `Message` instance, but in the [source code it accepts](https://github.com/python-telegram-bot/python-telegram-bot/blob/master/telegram/ext/filters.py#L114) only an `Update` instance. What is right? Should the Wiki be updated (and can I update the accused page)?
