The MDI to dock widget refactoring renamed the PDM class RimMdiWindowController to RimDockWindowController, and with it the class keyword written to the project file. Previous versions of ResInsight have no factory entry for DockWindowController, so the window controller of a plot is never created and the plot is silently invisible when the project file is opened by such a version. Keep DockWindowController as the keyword written for the window controller in use, and write the main window id a second time using the old keyword. RimViewWindow now has two child fields, the previous keyword WindowController holds the compatibility object and the new keyword DockWindow holds the window controller in use. Previous versions read the compatibility section and ignore the unknown DockWindow field, current versions read both and keep them in sync in dockInWindow(). RimMdiWindowController_OBSOLETE owns the keyword MdiWindowController and is derived from RimDockWindowController, so project files written by intermediate development versions using DockWindowController in the compatibility section are read into the same field without a type mismatch. RimDockWindowController::initAfterRead() restores the window controller in use from the compatibility section, covering both file layouts. The dropped geometry fields are harmless, RimMdiWindowGeometry::isValid() returns false and the previous version falls back to a default subwindow size, which is the same path the 3D views already take.
