ISLisp Emacs support

Thanks to [kenichi sasagawa](https://github.com/sasagawa888/eisl) for creating [eisl](https://github.com/sasagawa888/eisl) , a great free software implementation of the ISLisp programming language. Sadly, there were not support for Emacs.. until now! After 1(busy) year, the [merge request](https://github.com/melpa/melpa/pull/7745#event-7453898513) for MELPA it's done, and now it has fully support with these two packages: * islisp-mode\]([https://melpa.org/#/islisp-mode](https://melpa.org/#/islisp-mode)): major mode for editing files * inferior-islisp ([https://melpa.org/#/inferior-islisp](https://melpa.org/#/inferior-islisp)): REPL integration with Emacs The code is in the repo: [https://gitlab.com/sasanidas/islisp-mode](https://gitlab.com/sasanidas/islisp-mode) Happy hacking!

From the [EISL Repo](https://github.com/sasagawa888/eisl#have-fun-with-lisp): > I want to convey the fun of Lisp to boys and girls around the world. It's fun to create. Peace is wonderful. Let's end the war. I'm in tears. ## *Lisp = Love*
