Restored tutor prompt by emulating the old prompt interface

[DavyLandman]

In the future we could consider generating input streams where we pipe commands to, but that would still be messy, since we have to intercept the eval results. and the current tutor interface expects us to not print the repl prompt on application/rascal+stdout map, so we would also have to change that.

so instead, this PR is the smallest thing I could do to get it to work as it used to.

Only missing commenting back in the use of "repl.prompt()" seems to be missing. In rascal code. I'll look it up later if it's hard to find.

@jurgenvinju I think now everything it working again in this simulation, shall we merge it?
