This adds the actual switch to turn on Hardcore Mode to the settings tab of the Achievements dialog. It is accompanied by a large tooltip warning explaining what it does and when it can be enabled.
The switch is only enabled to be turned on when no game is running, so that games are started in hardcore mode and can only be loaded via the console's memory card, as in the original hardware. Hardcore may be turned off while a game is running, but cannot be turned back on until the game is disabled.
The toggle trigger for hardcore mode also automatically disables the settings that are not allowed during hardcore mode.
Finally, the original flag in AchievementSettingsWidget to set whether things are enabled in hardcore mode (primarily Leaderboards) is replaced with the actual Hardcore Mode setting.
This widget will be used in several places to notify the player that a feature has been disabled because hardcore mode is on. It includes a button to open the Achievement Settings so that Hardcore Mode may be turned off. Also included is the framework required to open AchievementsWindow specifically on the Settings tab.
A new tab is added to the Achievements dialog to chart out the leaderboards in a table. Each row of the table contains the leaderboard information and up to four relevant entries, varying based on how many entries are in the leaderboard, whether or not the player has a submitted score, and where in the leaderboard the player's score is.
Expanded the use of the lock mutex already used for loading the player's existing unlock status to guard against races involving the Achievements dialog window reading from data AchievementManager might be in the process of updating. The lock has been exposed publicly and the AchievementsWindow uses it in its UpdateData method, and anywhere else that might modify data used to render that window has also been wrapped with it.
AchievementManager now has a SetUpdateCallback method for providing a single universal callback for anytime something important changes in the achievement state, such as logging in/out, game load/close, or events such as achievement unlocks. AchievementsWindow sets this callback in its own init to its UpdateData method so that the AchievementsWindow gets updated when one of these changes takes place.
This widget is a tab in the AchievementsWindow that displays the player's current achievement progress: which achievements are locked or unlocked, and the progress of achievements that have progress metrics.
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).
AchievementSettingsWidget is a dialog widget in AchievementsWindow for handling RetroAchievements settings in the user interface. This class contains the physical layout, widget connections, load/save functions and button responses. AchievementsWindow now has a tabbed list that this is inserted into; other tabs will be in a later pull request.
AchievementsWindow is the dialog box that will eventually contain the settings and progress data for RetroAchievements on Dolphin. This adds the barebones dialog, and connects it to MainWindow's MenuBar.
