libcommon|SaveInfo|SaveSlots: Init save system in G_CommonPreInit, SaveSlots updates the game menu
Ideally the game menu widgets would observe SaveInfo changes directly, however this would require a new special purpose menu widget. For now it is easier to let SaveSlots assume responsibility for updating the game menu and thereby removing the need to manually force a SaveInfo update each time the save/load menu is opened.
