Evgeny Grechnikov (Diamond) 827172f6c0 * pic4, rdsave, cpuid: size optimization 
* @ss: decrease used memory & time requirements, size optimization
* @panel: if there is only one window, Alt+[Shift+]Tab activates it
* jpegview: IPC service to unpack JPEG data for other apps
* chess: bmp-file is now inlined
* @ss, chess moved to more appropriate place in file structure
