Local dev watch mode

[mikemitchel]

This changes the local front end dev environment to use a dev.sh script that allows for local front end dev changes to antidote-web and antidote-ui-components to be seen in the browser with a page refresh rather than restarting the docker container.

Current Steps to set up this environment:

1. uncomment line Guacamole mouse tracking isn't working with tabs #50 in rollup.config.js to get the correct Terminal (due to npm link below)

2. npm run dev from the src/ directory

• installs dependencies
• links local antidote-ui-components sibling repo to antidote-web node_modules
• cleans up and recreates python templates
• starts container

3. npm run watch from the src/ directory after step 2 completes

• starts rollup.js bundler in watch mode, will re-bundle on local dev changes
• volumes map in docker-compose.yml line Fix iframe reference/path #20 copies any updates to the container without restart

TODO:

• Allow style changes in a local nre-styles repo to also be updated via .less watch mode, possibly this https://www.npmjs.com/package/less-watch-compiler
• Automatically start rollup.js in watch mode
• Handle update to rollup.config.js base on dev mode being used (with linked npm sources or not)
• Make npm link for components optional?
