* Added TrailLayouter with Sugiyama dependency layouting * Layouter supports horizontal and vertical layouts * Added basic ui to graph view for showing incoming and outgoing paths * Added depth slider, with infinity at maximum * Disable trail ui when not available * Added trail messages to undo stack and only use last one when undoing * Added QtGraphLineBezier for trail graphs and refactored other line types * Disabled edge activation for trail layouts, shown only visually * Highlight all connected edges when hovering a node in trail layout * Use different color when highlighting call edges for better contrast * Fixed BucketLayouter issue when edge does not leave node * Increased click area for angled edges bug id = 249 337 fortune cookie message = Answer just what the heart prompts to you.
