ci: set NODE_ENV, fix out of memory issue, fix hot reload bundling

* ci: test docs-publish

* Specify to use prod

* Babel should transpile with env set by webpack

* chore: production defaults to true; set in --env.production by cli

* Remove lingering merge issue

* Add minimification plugins

* Need relative URLs to find root assets

* Default public url to forward slash in define plugin

* Don't wrap w/ react-hot-loader if we're building for production

* No need to log extensions

* Minimize using terser; and minimize css

* Import redux from es; this bypasses commonjs as import and fixes our "production build" warning

* Split commone webpack build for now to test hotfix

* postfix slash

* undefined safe env access

* Try to fix node_env prod issue w/ redux

* Set NODE_ENV production for all prod builds

* Syntax error

* nix tests

* Increase max amount of available memory

* Don't run bundle analyzer by default
