Minor site suggestion regarding NG and bugs

[Nick Sabalausky]

On whatever page(s) on digitalmars.com or d-programming-language.com refer 
to the newsgroups, there should probably be a note (with a link) indicating 
that bug reports should be posted to bug tracker rather than the NG. And 
also that "digitalmars.D.bugs" is just a mirror for the issues on the 
tracker and that posts shouldn't be made dirctly there. We're confusing a 
lot of people because of that.
