Node v12 and other fixes

Support Node 12, drop old nodes, refactor

Looks like several things I thought would be called aren't. So clean all that up.

Also fix some security issues that Github was complaining about.

v1.0.11: Binary packaging, no more semantic-release

This version introduces binary packaging. This should make it easier to install on Windows, OSX, and Linux hosts that don't have a full development environment installed. It also does away with semantic-release as it doesn't do a very good job coordinating with node-pre-gyp.
