Boris Zbarsky 4f2844b1a2 Bug 778150 part 3. Default attributes to infallible. Allow annotation of fallible attributes in WebIDL. r=peterv
The valid annotations are [Throws], [GetterThrows], and [SetterThrows], which can all either take no value or
be set to MainThread or Workers if the throwing behavior is only happening on main thread or in workers
