nokogiri > hpricot

Hi There! 

We found some problems with `hpricot` and Rails >= 3.1.  The good news is that `nokogiri` is a drop-in replacement for the use-cases in `Route53`, so we upgraded.  I haven't tested all `Route53`s methods, but I can confirm that record addition and deletion work, and the project was patched uniformly.

Thanks!
