Added _appletGetOperationMode() and _appletGetPerformanceMode(). In appletInitialize(), use _appletGetOperationMode and _appletGetPerformanceMode(). Also use _appletGetCurrentFocusState() in appletInitialize() with a global field even for non-application-type. Added _appletSetOperationModeChangedNotification/_appletSetPerformanceModeChangedNotification and use these in appletInitialize(). Added appletGetOperationMode(), appletGetPerformanceMode(), and appletGetFocusState(), which load from cached state fields. Handle notifications in appletMainLoop(). Added appletOperationMode enum. Imported applet hooking from libctru.
