Bugfix: NullPointerException when initializing the EclipseTheme together with the glass extension.
Added an annoying dialog, warning developers from using the Core API.
Bugfix: registering a Dockable that was already marked as the focused Dockable did not update the state of the DockTitles of said Dockable.
Added a new tutorial showing how a floating SplitDockStation can be created. Also modified the way LayerPriorities are merged, because the original implementation was not coping with the floating SplitDockStation.
Rearanged the tutorials, should be easier to navigate now.
