Subject: Add Ajc164Tests::testMultipleXMLFiles

While researching how and what to document for AJJ option
'-xmlConfigured', I needed to find out what happens in case of multiple
XML config files. Result: They are merged. the new test case for the old
1.6.4 release verifies and documents that. It can also serve as an
example for reference in case of user questions.
