TOOLS: Added engine patch for use with skycpt and updated skycpt README

This patch removes the description for required code modification to sky engine for generation of RESET.* files from the README and places it into a patch file. This patch also adds two modifications which are required to get RESET.* with current codebase not mentioned in the README.

-4) Change scummvm/sky/logic.cpp, function fnSkipIntroCode
-	so that it calls _skyControl->doLoadSavePanel()
+4) Apply the supplied skycpt-engine.patch to a clean copy of the ScummVM
+   codebase. This modifies the sky engine to allow savefiles to be generated
+   containing the required data for the skycpt tool.
 5) Compile the patched ScummVM.
-6) Start each of the BASS versions, enjoy the intro over and over again.
+6) Start each of the BASS versions with this patched version, enjoy the intro 
+   over and over again.
 	Afterwards, it'll automatically show the load/save dialog where you save the game.
-7) Rename the Savegame files you created to "RESET.*", depending on the version.
+	Except for Demo (v0.00356) which lacks the dialog, so this will autosave to slot 1
+	at the end of the intro.
+7) Rename the Savegame files you created (SKY-VM.000 etc., not the ASD or SAV 
+   file) to "RESET.*", depending on the version.
 	e.g. RESET.288 for v.0.00288
 8) Rename each file with a ".gz" suffix and run gunzip on it.
    This removes the ScummVM gzip savefile compression.
