Moved Util.maskVersion() to the XmlaBaseTestCase, since it's a test utility and shouldn't be outside of testsrc.  Also switched to using a regex replace to avoid some possible false matches
(when the version string appears in other contexts).

    (cherry picked from commit 38f5d67)
Merge pull request #115 from mkambol/laguMaskVersion
