Subject: [PATCH] node: WritableStream.write() should use a union for
 Buffer|string

I'm converting a node program I originally wrote in JS to TS, and
without this, the following pattern causes tsc to error out (tested
under 1.6):

```
let buf = current.read(); // current is a ReadableStream
if (buf !== null)
    output.write(buf);
```

With:

```
src/bin/cat.ts(28,17): error TS2345: Argument of type 'string | Buffer' is not assignable to parameter of type 'string'.
```
