XMLUnit for Java and XMLUnit.NET 2.5.0 Released

This release makes CommentLessSource and friends use XSLT 2.0 under the covers and adds new methods to override the XSLT version being used.

The full list of changes:

• CommentLessSource, DiffBuilder#ignoreComments and CompareMatcher#ignoreComments now all use XSLT version 2.0 stylesheets in order to strip comments. New constructors and methods have been added if you need a different version of XSLT (in particular if you need 1.0 which used to be the default up to XMLUnit 2.4.0).
