end: rewrite; save the RAM-disk on shutdown reliably

- merge end/light into a single modern end.asm, drop the unused
  image-based variant (back.raw)
- autosave writes the image back to the boot medium in place
  (SF 18.6 with ecx = 0) instead of spawning rdsave and hanging on
  its dialog; a failed save cancels the shutdown
- settings unified into app.ini [RDSave] (was rdsave.ini [settings])
- autosave is skipped when libini is missing instead of crashing
- locales ru/es/en via encoding.inc, -dlang from the Tupfile

-; and the chosen ID is checked in every incoming packet.
-;
-; Alongside the mouse report, the parser also maps the touchpad (Windows

-; Each Tip Switch opens a new finger block; the absolute X and Y that follow
-; it belong to that finger; Contact Count and the Button-page fields of the

+; GIF LITE v3.0 by Willow
+; Written in pure assembler by Ivushkin Andrey aka Willow
+; Modified by Diamond
+;
+; This include file will contain functions to handle GIF image format
+;
+; Created: August 15, 2004
+; Last changed: June 24, 2007
+
+; Requires kglobals.inc (iglobal/uglobal macro)
+; (program must 'include "kglobals.inc"' and say 'IncludeUGlobal'
+; somewhere in uninitialized data area).
+
+; Configuration: [changed from program which includes this file]
+; 1. The constant COLOR_ORDER: must be one of
+;    PALETTE - for 8-bit image with palette (sysfunction 65)
+;    MENUETOS - for MenuetOS and KolibriOS color order (sysfunction 7)
+;    OTHER - for standard color order
+; 2. Define constant GIF_SUPPORT_INTERLACED if you want to support interlaced
+;    GIFs.
+; 3. Single image mode vs multiple image mode:
+;    if the program defines the variable 'gif_img_count' of type dword
+;    somewhere, ReadGIF will enter multiple image mode: gif_img_count
+;    will be initialized with image count, output format is GIF_list,
+;    the function GetGIFinfo retrieves Nth image info. Otherwise, ReadGIF
+;    uses single image mode: exit after end of first image, output is
+;    <dd width,height, times width*height[*3] db image>
