Requirement draft updated

All,

as a result of the decision to for the time being handle all 
rtcweb/webrtc requirements in one doc 
(<http://datatracker.ietf.org/doc/draft-ietf-rtcweb-use-cases-and-requirements/>) 
I've updated the draft requirement document 
(<http://dev.w3.org/2011/webrtc/editor/webrtc_reqs.html>). It is now 
almost empty.
