AuthLogger causes messages from using apps/libraries to go to authentication.log as well

Importing UbuntuOne disables: qWarn, qDebug, console.log, QML errors
Setting U1_DEBUG=1 re-enables console output for qDebug and console.log. It additionally logs all messages to ~/.cache/ubuntuone/log/authentication.log

This bug was fixed in the package ubuntuone-credentials - 14.04+14.04.20140306
