[JDEV] Again: renaming JabberBox

[Jeremie <jeremie@jabber.org>]

I didn't really like xrouter or anything *router all that much, just
didn't jive with me, but I couldn't think of anything better... 

But, Sean came to the rescue and suggested "ether", which became "etherx" 
to represent "network shared XML" of some sort :)  It works out nicely
since transports "plug in" to etherx and pass "packets" around on it. 

So, I'll rename it to etherx tonight unless someone has a better
suggestion.
