Update Emacs keybindings

[jarmitage]

The way cybin-mode defines keybindings makes it kind of difficult to customise since it uses this prefix thing:

https://github.com/efairbanks/cybin/blob/91a797bf23b961890f9b2259b04d6ed724117baa/cybin-mode.el#L300

But anyways, it would be good to have:

(define-key result-map (kbd "<C-return>") 'cybin-send-paragraph)
(define-key result-map (kdb "C-c C-q") . cybin-kill-process)
