v0.1.2-rc.0

• Probably the last version to support Node.js 6. This version of Node.js is EoL for over a year, a lot of libraries we use dropped support and almost no one uses it anyway
• Updated dependencies to fix a number of security warnings (#22 by jegli)
• Moved customized dependencies to their own scoped npm packages, instead of github tarballs, to make integration in development workflows easier and reduce errors from old .npmrc files
• Create clearer log messages during startup (#9 by ryanholder)
