Why not use Node.nodeType for checking nodeType equality in htmldomapi.ts ?

[Fujihai]

In snabbdom\src\htmldomapi.ts，I think use Node.nodeType for checking nodeType equality is better.

Usage

before：

function isElement(node: Node): node is Element {
  return node.nodeType === 1;
}

function isText(node: Node): node is Text {
  return node.nodeType === 3;
}

function isComment(node: Node): node is Comment {
  return node.nodeType === 8;
}

function isDocumentFragment(node: Node): node is DocumentFragment {
  return node.nodeType === 11;
}

after：

function isElement(node: Node): node is Element {
  return node.nodeType === Node.ELEMENT_NODE;
}

function isText(node: Node): node is Text {
  return node.nodeType === Node.TEXT_NODE;
}

function isComment(node: Node): node is Comment {
  return node.nodeType === Node.COMMENT_NODE;
}

function isDocumentFragment(node: Node): node is DocumentFragment {
  return node.nodeType === Node.DOCUMENT_FRAGMENT_NODE;
}

I guess it would not make much of a difference. If you want to submit a PR I will merge it.
