JavaScript Modules v0.7.1

This is a small developer experience release:

• New JavaScript Modules are created with a docker-compose.yml file to start Jahia more easily. (#320)

  Use npm init @jahia/module to create a new module with the improved local setup, or copy the file from GitHub.

• Performance: insert <link rel="modulepreload"> to improve client-side JS load performance. (#349)
