This also moves a lot of display code to its own file
It's unclear whether the displayed code should also change. Leaving it unchanged helps indicate that execution will still proceed from the lowest level of the stack. Showing it changed helps provide the context of the call stack. This shows it changed.

It can be very confusing to see the full body of the method but actually
be in a method that does something like this:
%1 = (#self#)(x, default_args...)
return %1
because as soon as you step a line you discover you're done with the
call.
This takes a much stricter approach: any line number not observed is missing. It then performs some analysis of missings and replaces them with values when there is only one possible answer. For truly unknown lines, no line number is printed. (And no breakpoint info.)

This came up in a method that had nested conditionals and/or loops
This is pretty complicated so it's worth testing & explaining. Also generalizes the line number correction to allow any number of skipped lines as long as they remain in register.
This has long been needed. Obviously this is just a stub, needs many more tests (for edit mode as well as interpret mode)
This is more consistent with Debugger and probably easier to see.
This is particularly needed when Base.active_repl doesn't exist.

This adds a new mode that's rather fun. Try entering a command at the REPL and then hit Meta-i (on the same line, don't hit Enter). Then, for an intro to what can be done type
?.This requires timholy/Revise.jl#243, fully up-to-date JuliaInterpreter, and incorporates #60.
