Made change to the specification.

I've done it this way. The 'progress' and 'load' events are only  
dispatched if a preflight request has been made.

Added a note explaining the fields are mutually exclusive. Would it be  
useful to note that (origin, url, method, header) form the primary key of  
a cache entry? Since it's never needed by the specification in that way I  
didn't add it, but let me know.
