Create verbose_debug_log.txt where we log absolutely everything

[plocket]

We'd need to replace all the console.logs with a function that logged to the console, but also saved in the verbose debug doc.

• [ ] Label each log with its purpose and/or placement
• [ ] Still log to the console
• [ ] Log cucumber output

It'd also be nice (but not critical) to have nice indentation that matches, but that might be handled in a different issue.
