Some dep updates

* Reinstate *toobusy-js*... at least one of their timers has been fixed on shutdown. See OpenUserJS#354, OpenUserJS#353, OpenUserJS#352 and base issue of OpenUserJS#345 ... loosely related to OpenUserJS#249 and attempt to address OpenUserJS#944 with a work-around... VPS should be faster than our old one so perhaps the timers don't make as much of a difference. Start with our old default lag value... this may introduce too many 503's again but hopefully not
* Retested delete op
* Bug fixes, tests, and docs updates... please read their CHANGELOGS
* Shutdown the server on SIGINT
* Modify db closure to not have dependents
