Custom Hash Function

[blond]

I need to use custom hash-function for useHash: true option.

To copy images with unique names to a folder I used borschik with freeze option.

Hash-function in borschik different from hash-function in this package.

Let's do hashFunction option?

By Default:

hashFunction: function (contents) {
    return crypto.createHash('sha1')
      .update(contents)
      .digest('hex')
      .substr(0, 16);
}

For borschik:

hashFunction: function (contents) {
    return crypto.createHash('sha1')
        .update(contents)
        .digest('base64')
        .replace(/\+/g, '-')
        .replace(/\//g, '_')
        .replace(/=/g, '')
        .replace(/^[+-]+/g, '');
}

How about being able to pass a function to the existing useHash option? PR welcome.
