Enable CORS and allow all origins in dev-mode (#553)

The runQuickstartsFromSource.sh script was getting its PING
requests blocked because of CORS, making it look like the
quickstart was infinitely loading. To fix this, I enabled CORS
explictly on all the Quarkus quickstarts, and allow all origins
in dev mode (runQuickstartsFromSource.sh run the quickstarts
in dev mode).
