SCI: Rewrote the save/load code, see also patch #2687400.

The new format is incompatible with the old one, and is still subject to
some further changes. Also, regressions are quite possible, so watch out.
Finally, the new code still contains some TODOs and FIXMEs. Several of
these will be more or less automatically resolved once other code gets
C++ified.
