Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Gui reorganization and changes; partial implementation of floating widgets. Moved contents of mde/gui/WidgetData.d elsewhere; new gui/WidgetDataSet.d and gui/types.d modules. Changes to widget/createWidget.d Partially implemented FloatingAreaWidget to provide an area for floating "window" widgets. New DebugWidget and some uses of it (e.g. bad widget data). Decoupled OptionChanges from Options.
