Game script (bytecode) decompiler

First output!

I finally have some actual output working. It's only a proof of concept right now, but it's a nice start.

Here is the output the decompiler generates for one of the short Sam & Max scripts - one of the scripts I used for the code flow testing (link points to the graph for that script):
C:\scummvm\gsoc2010-decompiler>decompile -escummv6 script-33.dmp
VAR_GAME_LOADED = 0;
var173 = var177;
var177 = 874;
Unknown opcode 6B99 at address 00000018
Unknown opcode 66 at address 0000001A
It only does these simple assignments for now - everything else is left unknown - but like I said, it's a start.

The opcodes it complains about are cursorCmd_Image and stopObjectCodeB, since I don't handle those yet.
