Let's set up a mailing list for coordination with ECMA and Web IDL discussion

ECMA TC39 (the group responsible for ECMAScript) has expressed a  
strong interest in having a list for joint discussion with the W3C,  
and particularly the Web Apps WG. And they are especially interested  
in review of Web IDL. I suggest we set up <public-scripting@w3.org>  
(name suggested by Mark Miller) as a list managed by the Web Apps WG  
for both purposes - discussion of Web IDL, and other scripting-related  
coordination issues. I think this would be better than the massive  
cross-posting we've experienced over the past few days.

Does this sound like a good idea to everyone? If so, how quickly can  
we get it done?

Maciej
