Adds autofill detail tokens to the autocomplete attribute

Inspired by Jason Grigsby and Christian Heilmann, this update adds autofill detail tokens to the autocomplete attribute.

Good idea!

Lovely! I was about to make the same PR since Atom uses this list.

But there is one problem, I think: looking at <input> - HTML | MDN I see that you did not include "on" and "off".

@mcdado, yes, it's a nice +1 for both Atom and Brackets.

I intended to include the on and off values, but I misread the WHATWG standard for the autofill anchor mantle.

When autocomplete is wearing the autofill anchor mantle, on and off shouldn't be combined with autofill detail tokens — e.g. autocomplete="on street-address".

The values on and off are still part of the spec, even though off's usefulness is debatable, and should be included as values.

Thanks for helping me rethink this!
