synccharts.text: some modifications in the setup of the Actions Xtext tooling (scopeProvider configured to be employed as a singleton, more minor stuff)
edu.umd.cs.piccolo: some more refactoring of SWTGraphics2D class to support SWT RGB color definitions, little change in PSWTText allowing to specialize this class easier.
core.kgraph.text + klighd.test: fixed bug in KGraphValidator attaching the "Train KNode" info markers, fixed similar bug in SizeEstimationTrainer, introduced SizeEstimationTestWithFailings, moved successful test case
de.cau.cs.kieler.klighd(.piccolo): fixed implementation of gridPlacement: grid placer now includes the size of the children to calculate the columnWidths and rowHeights instead of just evaluating their placementData
