Allow repls to run on the host (read desc)

I cool featue would be to give the user the option if they want to run the repl locally (so in their hardware, not on repls vm’s) the repl then uses the laptop/pc of the client to run repls (so they user gets more speed than just 0.5 cpu), but they are not able to store them on the cloud as a trade of (except for the hack, pro plan).
