Martin Kiewitz 54cac32003 Revert "SCI: Add workaround for uninitialized reads in Island of Dr Brain"
This reverts commit ae8e4fa8e9.

This change is wrong in any case. It should be specific to temp
14+15 at the very least. I also did not get an answer on what
is actually happening internally. That's not how we should
add workarounds. My review was also still pending.

David Fioramonti ec1cfcbf47 SCI: Add workaround for uninit read during wordsearch in castlebrain
During the wordsearch puzzle (room 320 click left door) the
game will crash because of an uninitalized read of temp
variables in word::dispatchEvent (which gets called a lot),
if the player clicks the same letter or different letters
aggressively or holds down the enter key.

Fixes Trac#9783.

Colin Snover ba4fccdb26 SCI32: Add workaround for Torin/LSL7 running with subtitles only
Since these later SCI32 games weren't really designed to work with
subtitles-only message mode, if this doesn't work consistently or
breaks the games a lot in other places, the subtitles-only message
type could possibly be implemented in some other way, like by
messing with the game's speech volume global instead.

Colin Snover 262ef4de61 SCI32: Fix crash at end of Torin
This "fix" is more of a hack, in the interest of making the game
completable. The root cause is a combination of two problems in
the game scripts:

1. Blink::init expects to receive either 0 or 2 arguments, but
   it assumes that if it received *any* arguments, it must have
   received 2 arguments. This assumption is wrong, though,
   because--
2. soTorinWhoAreYou::changeState(0) calls
   poPecandEyes::setCycle(Blink) without including a second
   argument (the blink speed).

This ends up with the second parameter being some garbage, and
that garbage gets sent to kRandom which then complains about
receiving garbage.

The correct fix for this would be to fix soTorinWhoAreYou (in
script 51400) to pass a second argument to setCycle, but there are
not enough obvious spare bytes for a quick and easy patch, so this
workaround will have to do for now.

Fixes Trac#9779.

Also added in depth comments about the currently known variations
Returning the RNG seed is now implemented (although it seems no
games actually use this functionality, it seems to be just script
bugs).
Also remove Torin kRandom workarounds.
