Update diff to 1.0.7 and switch to the new WordsWithSpace diff algorithm

[papandreou]

This makes differences in whitespace (eg. CRLF vs LF) show up in the string diffs.

Previously this test

it('should show whitespace differences', function () {
    var err = new Error();
    err.actual = "foo\r\nbar";
    err.expected = "foo\rbar";
    throw err;
});

would result in this output:

1. should show whitespace differences:
   actual expected

foo<CR>bar

... which isn't really helpful. With this patch you'll get:

1. should show whitespace differences:
   actual expected

foo<CR><CR><LF>
bar

The issue is that jsdiff's Words algorithm ignores whitespace differences. kpdecker/jsdiff#22 added a new mode that does what you want in a test framework, namely a word-based diff that doesn't ignore any differences when formatting the output.
