dogtail.utils.run_tests and XmlTestRunner

This patch incorporates XMLTestRunner and adds an utility function to dogtail/utils.py to replace call to unittest.main().  This allows to add
a new and optional --xml arg.

Dogtail tests should then use

from dogtail.utils import run_tests

if __name__ == '__main__':
    run_tests()

instead of

import unittest

if __name__ == '__main__':
    unittest.main()

dogtail development has been stalled and it has been unmaintained for a few
years now.
Maintainers don't have future development plan so i am closing bugs as WONTFIX.
Please feel free to reopen the bugs in future if anyone takes the responsibility for active development.
