Fix slashes on Windows.

[XhmikosR]

There's a bug somewhere which results in backslashes in paths when building on Windows.

Maybe the name should be normalize slashes or something? I just wanted to keep it short here.

Fixes #2396

Is there anyone with a windows box who can verify?

Here's the output without this patch (trimmed) to get an idea:

My main concern is that I don't know where this bug comes from. Is it from metalsmith itself?

@XhmikosR, Have you submitted test:html in the package.json?

[XhmikosR]

@MaledongGit: what do you mean? If you mean the vnu addition, that's in #2469, which isn't ready yet.

[SEWeiTung]

@XhmikosR ：Well……I fetched the latest version of codes and I cannot use test:html, I want to know whether this is already added in the package.json or not. Otherwises I'll merge it into the repository ;)

[XhmikosR]

If you mean the slashes PR, that's ready. The vnu PR is not ready,I list the TODO there.

The process.platform check seems inconsistent now since in summary.js I don't do the same.
