This works by simply keeping backups the entire relevant state of the Wobbly project after each action and rolling back to such states on undo/redo. This is feasible since Wobbly's internal state is not very memory-intensive. A drawback is that all list or table models have to be repopulated from scratch, so selections in dialogs are cleared on every undo/redo. This could be improved later on by saving the UI state before a rollback and restoring it after it is completed. Fixes dubhater#15 .
