Comment 6 for bug 1685003

There were some bugs in the logging code such as verbosity being enabled by default; I went and fixed this in http://bazaar.launchpad.net/~variety/variety/trunk/revision/610

Specifically, the default setup without any -v arguments leaves stderr as warning and about only, while variety.log is kept at INFO.

The commit details:

- Fix options.verbose defaulting to 1 (equivalent of -v)
- Don't spam INFO to stderr unless at least one -v is given, as many systems forward this to ~/.xsession-errors and/or syslog
   - However, leave variety.log at INFO-level to aid us in debugging.
   - This fixes https://bugs.launchpad.net/variety/+bug/1685003
- Fix debug logging for VarietyWindow, ThumbsManager, and ThumbsWindow requiring -vvv or -vvvv to enable (decrease these by one)
