Removing @author tags

[Andrus Adamchik]

I'd like to suggest stripping @author tags from all Java classes. In a  
mature project like Cayenne they make little sense, as many people  
have touched most files over the years. They only create false  
ownership perception. As my name is on most of the classes, I figured  
it would be most appropriate if I suggest that myself.

Also IIRC there have been discussions in other places at Apache that  
mentioned @author tags as a potential for developer legal liability  
(as you know, one of the major goals of the ASF is to shield  
individual contributors from such liability). I am personally less  
concerned about this particular aspect, still figured I'd mention.

Thoughts?
