Subject: [PATCH] config: add support for appending a 'spawn' argument to key
 bindings

A key binding may now have an optional ':<cmd>' string appended to the
key.

This is intended to be used like so:

  pipe-scrollback:sh -c "cat > file"=Print

TODO: we still only allow one *action*. Meaning you still cannot
specify multiple pipe-scrollback bindings, for example.
