Improve logging / remove debug messages

[KlemenDEV]

There seem to be some logging messages that are printed. This one is printed especially often: https://github.com/andrewauclair/ModernDocking/blob/3fa9a8c118ba5ae70c827d23f2ff598799c3274f/docking-api/src/ModernDocking/floating/DockingOverlay.java#L391

This should probably be removed or put under some sort of parameter
