ui: Show title bar at top and scroll bar at bottom in code view snippet list if necessary (issues #432, #479)
* Show title bar at top of snippet list if first file is cut off * Show scrollbar at bottom of snippet list if last snippet if cut off and horizontally scrollable * Extended scrollRequest API to different ScrollTarget modes * Fixed snippet extension broken if maximized first * Split off title bar functionality to separate class QtCodeFileTitleBar
