The REPL tab redirecting to tryclojure.org is down no longer a repl #317

It redirects instead to a non related website.
It should redirect to another simple clojure repl.
I see two quickly :

• https://repl.it/languages/clojure
• https://clojurescript.io/
  The first has online source files and really clojure
  The second is with parinfer if wanted and with the useful doc on the click of a button, but is clojureScript.
  Anyhow, it only needs a change in
  ./src/foreclojure/template.clj\45: ["http://try-clojure.org" "REPL" true]
  So when decided, I could make a PR if needed.

Thank you for your time :)
