wiki reorganization

[Rahul Sundaram]

Hi

Anticipating the upcoming merge of Fedora Core and Extras I have been 
removing the references to Fedora Core and replacing it with appropriate 
terms throughout the wiki but I would need suggestions on how to handle 
pages within the /Extras namespace.  Would moving them to /Packaging 
make sense? Can we considering dropping the ACL's in the packaging page 
and just add a note on top that changes needs to be handled by the 
packaging committee?
