New cheats

[cocus]

Hi!
I just stumbled upon this project. I've quickly hacked up two new entries on the CheatController that make meat saws and land mines to not trigger. It's really hacked up, and since these weren't part of the original game, I didn't comply to the naming schemes and the variables. I want to explore how to do this properly.

So, just for the non-fatal meat saws, I have the following:

 CheatController* CheatController::ctor_40FBF0()
 {```

As you can see, the controller callback doesn't have the OG game address since this is new. Neither does have it the variable `sEnableNonHarmfulMeatSaw`. Not sure if this is okay, or if I should use ALIVE_VAR. I don't think so, but what do I know? :)

Now, on the MeatSaw sources, I've done this dirty hack:
```diff --git a/Source/AliveLibAO/MeatSaw.cpp b/Source/AliveLibAO/MeatSaw.cpp

+        return;

     for (s32 i = 0; i < gBaseAliveGameObjects_4FC8A0->Size(); i++)
     {
         BaseAliveGameObject* pObjIter = gBaseAliveGameObjects_4FC8A0->ItemAt(i);

I'm not sure if there's a better way of export these variables and pass them around.

In any case, I'm open to your feedback before proceeding further. Another stuff I was thinking about are some other cheats that give you grenades or rocks. I've had a look at the source that picks up grenades/rocks/meat but it was still too cryptic to make a quick hack.

Thanks!

Hello - we are in the process of merging both engines so I would recommend holding off until that point as it will effectively need to be rewritten.
