Adds the ability receive notifications from forum to Telegram.
P.S.: Notifications cannot be delivered to Telegram if default forum alert is disabled. For supporting all available alert types (include alerts from custom addons), this addon listens forum built-in alerts.

The project source code is hosted on GitHub. I am happy accept your PR or review issues.
I spent my free time developing this addon, and will be happy, if you donate me some money on coffee.
