* Normalize logs
All classes that could have their loggers inherited from their fathers had their own loggers deleted;
Most loggers didn't have to be static, so most of them were normalized so that they wouldn't be;
All loggers are protected now;
Static logger's name are now 'LOGGER';
Non-static logger's name are now 'logger';
New class DbUpgradeAbstractImpl created so that all Upgraders extend it and inherit its logger
