* bugfix for Telegram chat_ids
- Negative `chat_id`s for groups.
- Include `chat_id` in event data.
- Handle KeyError when receiving other types of messages, as `new_chat_member` ones, and send them as text.
* unused import
* fix double quote style, fix boolean expr, change warning msg
* mistake
* some more fixes
- fix if condition for msg bad fields.
- return True for a correct but not allowed or not recognized message: if not, the message arrives continuously.
- Allow to receive messages from unauthorized users if they come from authorized groups.
* support for `edited_message`s
- They come as normal messages, except for the 'edited_message' field instead of 'message'.
* telegram_bot and notify.telegram enhancements:
- Receive callback queries and produce `telegram_callback` events.
- Custom reply_markup (keyboard or inline_keyboard) for every type of message (message, photo, location & document).
- `disable_notification`, `disable_web_page_preview`, `reply_to_message_id` and `parse_mode` optional keyword args.
- Line break between title and message fields: `'{}\n{}'.format(title, message)`
- Move Telegram notification services to `telegram_bot` component and forward service calls from the telegram notify service to the telegram component, so now the `notify.telegram` platform depends of `telegram_bot`, and there is no need for `api_key` in the notifier configuration. The notifier calls the new notification services of the bot component:
- telegram_bot/send_message
- telegram_bot/send_photo
- telegram_bot/send_document
- telegram_bot/send_location
- telegram_bot/edit_message
- telegram_bot/edit_caption
- telegram_bot/edit_replymarkup
- telegram_bot/answer_callback_query
- Added descriptions of the new notification services with a services.yaml file.
- CONFIG_SCHEMA instead of PLATFORM_SCHEMA for the `telegram_bot` component, so only one platform is allowed.
- Async component setup.
* telegram_bot and notify.telegram enhancements: change in requirements_all.txt.
* Always register the view if a webhook exists.
* Return True if platform is set up succesfully, False otherwise.
* Remove the webhook when home assistant stops. Webhooks and long
polling are mutually excklusive. If a webhook is left after home
assistant is stopped, a polling telegram bot is unable to be set up,
on next start of home assistant.
