The Disabled state sits between Game Closed and completely Shutdown - stronger than the former, as it refuses to let a game be opened again until AchievementManager is restored (which only happens upon a fresh core boot) but it isn't completely shut down and will still allow the player to be logged in and access the achievement settings and their (global) achievement header.
Provided badges are turned on, if there's a player logged in their RetroAchievements icon will appear next to their player info in the header of the Achievements dialog. If they're playing a game, so will the icon for the game. Also performed some refactoring and reorganizing to the header as a whole so that it looks consistent whether a game is running or not.
This widget displays a header on the AchievementsWindow dialog above the tabs that shows the currently logged in user (if there is one) and the game they are playing (if there is one).
