* removed $throwExceptions (always throws)

* added DibiLogger, dibi::notify(), dibi::startLogger()
* miniprofiler dibi::$numOfQueries, $totalTime, $elapsedTime
* simplified DibiException, added DibiDatabaseException
* Dibi::nativeQuery splitted into DibiDriver::doQuery & nativeQuery()
* moved dibi::dumpResult -> DibiResult::dump()
* moved dibi::test() -> DibiDriver::test()
* DibiTranslator generates $mask
