[dom] Using [Exposed=Window] (#89)

According to Web IDL default global is primary global interface (Window), so there is no need to use [Exposed] only for Window:
http://heycam.github.io/webidl/#Exposed
but even if it is going to use them, then I see that for some interface is still missing:
DOMTokenList, DOMSettableTokenList, MutationObserver, EventListener. I'm not sure what should be done for MutationCallback (callback function http://heycam.github.io/webidl/#idl-callback-functions), [Exposed] can/should be use here or not?

I check some other specs and most of them don't use [Exposed] only for Window (even in HTML, but see one exception HTMLHyperlinkElementUtils).
