Vanilla JS Module Starter

This just creates a super minimal JS file that is importable as a module.

• adds very basic webpack config to compile and minify modern js code
• defines alias to directly import from ./lib using @/your/path => lib/your/path
• adds common files to .gitignore
• configures babel
• adds eslint
• adds editorconfig
• adds nvmrc (maybe you should update)
• adds simple tests for Gitlab CI
• adds jest
• runs lint, test and build script before commit
• includes /dist/ folder so it can be installed directly
