+ Added "undo" library (undo namespace). + Moved UndoHistory to undo namespace. + Added Undoer and UndoersCollector interfaces. + Converted old UndoStream to UndoersStack class. + Added new "undoers" namespace and moved each Undoer implementation (classes to undo different actions) to "undoers" directory. + Added IO operations to "raster" objects (image, cel, layer, palette, mask).
