Use an enum for appletSetScreenShotPermission with info from wiki. Improved applet docs. Use _appletIsApplication() instead of _appletIsRegularApplication() in appletQueryApplicationPlayStatistics/appletQueryApplicationPlayStatisticsByUid. Added appletGetGpuErrorDetectedSystemEvent. Added support for the [7.0.0+] CreateApplication*ToStartForQuest cmds.
