CNetObjectEx_GameDataPrediction

```cpp
struct CNetObjectEx_GameDataPrediction
{
	int m_PredictionMask;
};
```
In 0.8, it should be merged as part of CNetObj_GameData.
It could enable and disable certain predictions through bitwise operation masks

example:
```cpp
enum
{
	NETPREDICTION_HOOK = 1 << 0,
	NETPREDICTION_MOVE = 1 << 1,
	NETPREDICTION_JUMP = 1 << 2,
	NETPREDICTION_CHAR_COLLISION = 1 << 3
};
```
