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).
