[+] Added DynamicSideWidgetViewer::sideViewerWidgetInterfaces() and DynamicSideWidgetViewer::sideViewerWidgets()
[+] Improved layout in side viewer widgets.
[+] Added setProjectMenuItemsTargetMenu(), projectMenuItemsTargetMenu(), setProjectMenuItemsBeforeCommand(), projectMenuItemsBeforeCommand() to ProjectManager.
[*] Project Management Plugin: Now uses the new projectMenuItemsTargetMenu() and projectMenuItemsBeforeCommand() functions in ProjectManager to determine where
                               project menu items should be placed. Previously this was hard coded.
Fix actions not showing properly anymore in DebugWidget.
