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.
