[support] Drupal site information

[Joel Willers]

At DrupalCon I found out about some file that is suggested to be removed that, if I recall correctly, will tell you the version of Drupal installed on a site. I can't seem to find that information now that I'm looking for it, and I'm afraid I might have dreamt it. 

Any suggestions? Psychiatrist? "If you're dreaming of Drupal, you have some serious problems. Still... wanna take a look at our website?"
