Resolve "Content-Security-Policy header does not respect CUSTOM_HOSTNAME"
Configures CSP directives in gitlab.yml based on CUSTOM_HOSTNAME. Webpack livereload requires this because connections to ws://CUSTOM_HOSTNAME:3808
are blocked by the CSP rules.
This also fixes a bug where webpack dev_server is sometimes set to false in gitlab.yml
even if USE_WEBPACK_DEV
is true.
Closes #42 (closed)
