config: piped master config inlined for workers

Configuration piped to master gets sent over to the workers
by means of inlining, by converting their cli argument vectors
to accept an inlined configuration.
This addresses part 2 of issue #43, instead of using IPC style
of passing in arguments to workers.
For sure, except that the else also has a comment, but I'll figure out how to add in the comments for both the if and else case.
