etc. to the different opcodes. Until now it has done so by casting the
pointer to an int32 (opcode parameters are represented as arrays of int32)
and then the opcode function casts it back to whatever pointer it needs.
At least in C there is no guarantee that a pointer can be represented as an
integer type (though apparently C99 may define such a type), so this has
struck me as unsafe ever since I first noticed it.
However, since all such pointers appear to point to the memory block owned
by the memory manager, we can easily convert them to integers by treating
them as offsets into the memory block. So that's what I have done. I hope I
caught all the occurences in the opcode functions, or we're going to have
some pretty interesting regressions on our hands...

and removed some of the references to global variables.
At this point I believe everything in the main game engine has been moved
into classes - not necessarily the correct ones, but still... However,
there is some stuff in the driver directory that need to be taken care of
as well.

Renamed the resource manager's open/close methods openResource() and
closeResource() to avoid confusion. (It was I who originally shortened
their names to open() and close(), but I've changed my mind now.)
Moved more stuff into Sword2Engine.

console from the SCUMM engine. I decided that would be easier than to clean
up the original console code.
Unfortunately there's a bunch of code that I just copied - a pretty lousy
form of code-reusal. It'd be nice if the console could be made part of the
Engine class, or something like that.
Most of the debug commands seem to be working. Some aren't relevant for
ScummVM, and some are a bit obscure so I'm not quite sure what they're
supposed to be doing.

touches a lot of the code, of course, and adds yet another global variable
(temporarily, I hope), but everything still seems to work.
Knock on wood.
