Consider switching to Oga

[colindean]

Oga is a new XML parsing library that doesn't have massive dependencies like Nokogiri does. Use it instead.

It was really quick to migrate to Oga. Change the instantiation, change the parse method, change how elements are identified, and change how attributes are accessed.

However, it seems to be a lot slower. Running some benchmarking now.

That, and this, are on MRI 2.1.2.

Nokogiri version on JRuby took almost a minute, too, and ran out of RAM.
