Two broken links in Intruction page of Scala Tour

[bruno-medeiros]

in http://docs.scala-lang.org/tutorials/tour/tour-of-scala.html

"processing of XML data" link is broken
so is "explicitly typed self references" (should it be http://docs.scala-lang.org/tutorials/tour/self-types.html ?)

[aaabramov]

Seems that there is no document that is named xml-processing.md (took from 404 link - http://docs.scala-lang.org/tutorials/tour/xml-processing.html).

So we need an advice to which page it should logically point. Or just remove the link.

Should be fixed with #854

Indeed it is fixed. Thanks again @ashawley!
