Errors with nokogiri 1.6.8.1

::Fixnum is deprecated

```

NOTE Can't try out nokogiri 1.7.0, due to rails 5.0.1 dependency problems. So wishing to see fix in 1.6.8.x series.

@kikonen I've already released v1.7.0 which addresses this.

If you have an issue with Rails's dependencies, you should open an issue there.

I've bumped #rails-contrib, not sure what else to do. We're not planning to do another release of the 1.6.x series
