Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Partially complete commit: code runs but context menus don't work. Moved WMScreen.createRootWidget to WidgetManager.createWidgets. Put childContext under a popupHandler widget. TODO: implement IChildWidget.setContent(Content) (see AParentWidget.d:237).
