Update README.md

Added apache configuration. Issue: however CalQlate-ws data is visible in the webapp, it is only the case when run in the internal Eclipse browser, when the index.html is started from the Navigator tab (file:///Users/mdeboer/Development/Java/ws/CalQlate/CalQlate-web/index.html). Whenever started as: http://localhost:80/CalQlate the alias seems to work, but sadly no data from the webservice. Something to do with the Same-origin policy??
