[progress-events] Update

I offered Charles to take over editing of the Progress Events  
specification and hopefully drive it to completion. Today I wrote a draft  
for ProgressEvent & company inspired by Charles' work:

   http://dev.w3.org/2006/webapi/progress/

I suggest we publish this as a Working Draft.


Relative to the latest Working Draft —  
http://www.w3.org/TR/2008/WD-progress-events-20080521/ — this has been  
changed:

* Allowed the ProgressEvent interface to be used for pretty much anything.  
This helps with HTML5 application caches.
* Defined a restricted subset of it for HTTP requests.
* Made it clear that for cross-origin requests these events present a leak  
of sorts.
* Event types are now suggestions rather than normative. Specifications  
will have to make the final call.
* Added the event type loadend as suggestion; used by XMLHttpRequest.

I still think the interface members have terrible misleading names and  
would happily fix that to make them more similar to the names used for  
<progress> if we can get agreement, but I guess it is too late for that.


Charles' editors draft can be found here:

   http://dev.w3.org/2006/webapi/progress/Progress.html

He made more changes but those have never been picked up by other  
specifications or implementations so I decided to not base it on that.
