SCI32: Read byte/string array values as signed in SCI2.1early-
KQ7 1.51 writes int16s from the save game catalogue into a Str
object, then retrieves byte 0 from the string and compares it to
-1. This happens to work out because (1) characters were treated
as signed in SCI2.1early and earlier, and (2) int16s in the save
game catalogue were little-endian.
In SCI2.1mid and later, this trick no longer works because
characters are treated as unsigned and get zero-extended instead.
Fixes Trac#9632.
