Update d8 preemption mode to support multiple files per line.  Each line is run

Also add support for comment lines, which start with '#'.

Please make sure you work with Christian to adapt the "Debug Preempt" testing

Since you already abstracted ReadLine() you might want to pull this out into a
ReadWord() function. That way the name of the function documents what you are
