fix: use the main prop for the application entry point.

npm start will now look at the main property for the entry point.  Port 8080 is now set as the default port instead of 3000.   This is a fix related to https://github.com/bucharest-gold/centos7-s2i-nodejs/issues/33\#issuecomment-382587104.
