libdeng2|SavedSession: Use absolute paths to SavedSessions in the "repository" index
Although the user's savegames will always exist in /home/savegames we should require that all game saving is done here. For example, Hexen uses a "base" savegame internally for storing the states of visited maps in a hub for the current game session. This built-in savegame should not be stored alongside the user's savegames.
