Can SpecialOperation be more simplified?

[saschanaz]

Currently SpecialOperation allows multiple keywords before RegularOperation:

SpecialOperation ::
    Special Specials RegularOperation
Specials ::
    Special Specials
    ε
Special ::
    getter
    setter
    deleter

This was required before #44 to allow setter creator void set(DOMString name, any value); but now it seems no IDL uses getter setter, setter deleter, etc.

So I think SpecialOperation can just be Special RegularOperation, what do you think?

Should probably also clean up the language in https://heycam.github.io/webidl/#idl-special-operations accordingly. And replace "five" with "four" while we're there.

But yes, this cleanup would make sense to me.

Also, it's not immediately obvious why stringifier and getter/setter/deleter are handled differently in grammar terms...

So now that we have CI that verifies the grammar stays LL(1), I'm much more confident to do a syntax overhaul/cleanup.
