AbstractViewerPanel

[tpietzsch]

• Split out abstract base class from AbstractViewerPanel from ViewerPanel. AbstractViewerPanel is used instead of ViewerPanel where possible. This will allow to re-use bookmark, bounding box, manual transform tools in BigVolumeViewer.
• Use scijava-listeners for ViewerPanel listeners
• Reduce usage of deprecated bdv.viewer.state.ViewerState
• make AbstractViewerPanel.align(...) public
