Export more map info and notes as code comments

[jpcompton]

This is a feature request to include more ancillary map elements (particularly but not limited to connector names) as comments in code exports.

My specific request comes from exploring the use of trizbort.io as a choice-based planning tool and concluding that the main drawback is that the eventual TADS output drops connector names, used in this situation as player choices.

I personally find TADS the most easy-to-read format when working in systems that aren't currently supported for export, but the request could apply to any code export and any map info that isn't currently exported because it doesn't correlate with any map code in a given format.
