Last commit: Tue May 22 22:39:52 2018 +0200	Jan Dankert	Fix für PHP 7.2: 'Object' darf nun nicht mehr als Klassennamen verwendet werden. AUCH NICHT IN EINEM NAMESPACE! WTF, wozu habe ich das in einen verfickten Namespace gepackt? Wozu soll der sonst da sein??? Amateure. Daher nun notgedrungen unbenannt in 'BaseObject'.
