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

Browse Source 
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.

v.0.00365: CD Demo
v.0.00368: Full CD version
v.0.00372: Final CD version
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.
