Andrea Rendine 64a02c162c Modified command destination for save
Export dialog replaces selection dialog, rather than overlapping it.
Closing it exits the panel and returns to current game.
Aborting Import dialog returns the player to the selection screen, so that s/he can save before trying to load.
