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

; EYES FOR MENUET
;
; Written by Nikita Lesnikov (nlo_one@mail.ru)
;
; Position of "eyes" is fixed. To close "eyes" just click on them.
;
; NOTE: quite big timeout is used to disable blinking when redrawing.
; If "eyes" blink on your system, enlarge the TIMEOUT. If not, you can
; decrease it due to more realistic movement.
;
TIMEOUT equ 5
