heavyiron 4daae89053 *kernel - fixes in 15.2 by Mario79 and 67 by mike.dld
updated sysfunc.txt
*programs 
         new icons and logo for CPUID and ICON
         added new version of @ICON and ICONMNGR
         fixes in iconedit and calendar from DedOK
         new algoritm of fill background in pic4
         all apps (fasm-writen only) rewriten to use common macros.inc for easy recompile in fastcall mode (there is a bug in https; run need rewrite to use common macros.inc)
         small fixes in build_all.bat script

; Z = X * SIN(yang) + Z * COS(yang) / 256
;
; Rotate around z-axis
; X = X * COS(zang) - Y * SIN(zang) / 256
; Y = X * SIN(zang) + Y * COS(zang) / 256
;
; Divide by 256 coz we have multiplyd our sin values with 256 too.
; This example isn't too fast right now but it'll work just fine.
