feat(emacs): Eshell stuff

- Fancify prompt
  - Shows success of last command.
  - TRAMP prefix is made distinct.
  - CWD is abbreviated.
- cd to project root (`cdp`).
- Imitate using `C-d` / send-EOF to exit.
- Opening popup shell puts user in insert state.
- Fixes TRAMP customisation.

Nicely done! }:3
