dc3de47b03 PixelPaint: Have layers and images send out notifications on changes 
We use this to automatically update the thumbnail in LayerListWidget
when you draw into a layer. We also use it to repaint the ImageEditor
when the image changes somehow. :^)

de85cd0907 PixelPaint: Start working on a custom layer list widget 
Instead of using a TableView to show the layer stack, let's build a new
custom widget for this purpose and give it some neat features!

This patch also introduces an ImageClient interface for Image to notify
interested parties about things happening. The LayerListWidget is the
first ImageClient and listens for "layer added" and "layer removed"
notifications. :^)
