Add REPL to console area

[fjenett]

For example this one:
https://github.com/albertlatacz/java-repl

Could live next to the console area (or be the console area).

Wow, this would be something nice! And the console will finally gain the long requested text input functionality too.

What about a clear button to clear the console during run-time (or otherwise)? It might especially be useful when there are a lot of print statements, and things start getting cluttered and confusing...

@joelmoniz .. do you want to give a fresh mode with a REPL a try as a warmup? You can base it on https://github.com/martinleopold/TemplateMode

@fjenett : Thank you. I'd love to!
