Add a default chat to the Telegram connector

A Telegram connection can now hold an optional default chat ID. When it
is set, both Telegram actions send there, the model is no longer asked
for a chat, and a chat it names anyway is ignored. In member mode each
member's own connection supplies their own chat. The same bot with a
different chat is a separate connection.
