Fix werkzeug request logging with the log panel
Fix werkzeug request logging with the log panel

Werkzeug will disable its default logging setup if another log handler
is already configured.  At some point the initialization order changed
and the logging panel's handler is getting added first now, so
werkzeug's request log will not be printed to the console by default. By
explicitly calling werkzeug's logger we now make sure it's initialized
before the logging panel's handler.

Fixes #33
