New unit test runner: Test::Unit::UI::Xml::TestRunner
I have created a new unit test runner that behaves like Test::Unit::UI::Console::TestRunner but can also create a xml file containing the unit test results.
Personally I think it can be quite useful, especially for processing unit test results with 3rd party tools.
This is my first patch so please forgive me if something is wrong :)
I have attached the patch below.
