commands: add bounce

Add a command to allow for reintroduction of messages into the transport
system. This means taking a message and forwarding it to new recipients
as is including original headers. The fact that the message has been
bounced is indicated by the prepend of *Resent-* headers in accordance
with RFC 2822. The bounced message is not stored in the sent mailbox.

Also add an `-A` switch to allow for bouncing using different account
than the one currently selected.

Also add default keybind and documentation entry for this command.

The mentioned RFC also recognizes *Resent-Cc* and *Resent-Bcc* headers
which might be an interesting continuation of this -- currently all
recipients are specified in *Resent-To*. Also more control over the
*Resent-From* header value could be implemented.

This command is strongly inspired by (neo)mutt's `bounce`.
