Create build script to simplify release process

[karissademi]

The process for creating a release is a bit cumbersome, requiring that a script be run for npm publishes and another manual .zip created for github assets. It would be nice if a single script could be run when a release is ready that would handle:

• versioning
• creation of the dist folder
• generation of the GitHub release package

This is not a high priority.

I think travis can do this: https://docs.travis-ci.com/user/deployment/releases/

Is there a way to change the package manager and compiler command from "Yarn" to NPM? Yarn stoped working correctly after upgrading to MacOS Mojav. (It is actually a Homebrew issue that is affecting Yarn)

I've also had some other issues with Yarn, so I'm fine with switching back to npm. I haven't upgraded to Mojav yet, so thanks for the warning on that!
