Rearranged parts of the Operation Stealth savegame loading routine.

- Emulating the Future Wars savegame loading routine and hoping for the best.
- Fixes an array out of bounds access when loading the global scripts.
Now the loading crashes in the mainloop in processSeqList!
But at least we got a bit farther this time. More fixing to come...
