[FR] "Start debugging" command

[marius311]

Big thanks for the work on the debugger to everyone involved, over the last few weeks/months its really transitioned for me from a "well I'm glad to know its at least there" to "I use this all the time" and its great!

Probably the biggest minor annoyance I've run into is the "Please run the debugger/interpreter in the REPL." thing. I have no background on why this is necessary, but it would be great to have just a "start debugging" command that takes the current inline command and debugs it (this would also solve that I'm often switching/reloading modules and I always forget to using Juno in new/fresh modules before starting to debug). Thanks!
