Leak to the log on other environment

[Jun Omae]

The logger library in Python is similar to log4j. The loggers have hierarchy with the period-separated names. The log messages are passed to the ancestor logger handlers. See ​http://docs.python.org/library/logging.html#logger-objects.

And, Trac uses the path of environment as logger name.

If the path has period, it will output to the ancestor logger.

Patch [80b89ce8/jomae.git].

How to reproduce

1. Create two environments named /var/trac/parent and /var/trac/parent.child
2. Enable logging on the environments
3. Run tracd -e
4. Access parent.child environment using your browser
5. Output to both log files on the environments
