Fresh start import of XoopsCore 2.6.0 from Sourceforge SVN

This import has no history, so for any historical research,
please use the sourceforge SVN. This is intended to give us
a fresh clean start as we continue the development of
XoopsCore 2.6.0 with some new tools and new techniques.
Updated xml files for unit tests so they would run with Doctrine.
Updated init_mini.php so it would be dynamic instead of hard coded.
Updated class\database\DatabaseFactoryTest.php to incorporate doctrine call.

log messages for further processing. Multiple logging processes can
