title: How to add version to file using gulp?
body: <p>I need to add version to file. e.g font.otf?v=452155</p>
  
  <p>I tried gulp-rename but it doesn't help.
  I need to add version after extension.</p>
  
  <pre><code>var time = new Date().getTime();
  gulp.task('addTimestampToFont', function(callback) {
  gulp.src('../../fonts/icons/Icons.*')
      .pipe(rename({
          extname: '?v=' + timestamp
      }))
      .pipe(gulp.dest('../../fonts/'));
  callback();
  });
  </code></pre>
