Piotr Synowiec 258c9680b2 feat(hello): optionally address the sender in the reply (#292)
Adds a `[Hello_Command] include_sender` setting (default off) that names the user the hello reply is answering, so a busy channel can tell whose greeting the bot picked up.

The mention takes the place of the random human descriptor, keeping the translated sentence intact, and is dropped when it would push the reply past the channel body budget. DMs are unaffected, and channel sender names are sanitized before being echoed.
