Switch from open module to opn?

Line 57 in 5e671fc

"open": "0.0.5",

Looks like open was deprecated in favor of the opn module.

Also, switching to opn would bypass this issue: https://nodesecurity.io/advisories/663

As the latest ESR (Firefox 60) supports WebExtensions only, I believe jpm itself is de facto deprecated.
