Description of problem:

  The default vhost (with the successful-server-installation message) is included in the base nginx.conf file, and cannot be deleted or overridden (except by more specific, non-default definitions) in conf.d/* files.

  Moving the default vhost into a conf.d file would make it easier for users to deploy different default vhosts without needing to modify the base configuration.

Version-Release number of selected component (if applicable):

  nginx-0.8.53-1.el5

How reproducible:

  100%

Steps to Reproduce:
1. Install yum package
2. Add a new default server definition in /etc/nginx/conf.d/
3. Restart server
4. Request page
  
Actual results:

  The page from the default your-server-was-successfully-installed vhost defined in /etc/nginx.conf is displayed

Expected results:

  The page from the dropped-in configuration should be used. (Requiring the user to delete or overwrite a specific file, ie. /etc/nginx/conf.d/default.conf, would be reasonable).
