[RFC] gameux.dll partial implementation

[Mariusz Pluciński]

Hi
The library I was working on last weeks - gameux.dll - is now partially
complete. IGameExplorer and IGameExplorer2 interfaces are working
and stores data in Windows-compatible format (attached tests confirm
it). Last two interfaces - IGameStatistics and IGameStatisticsMgr has
initial work done, but, as their task is only read and save data files,
it's not much work to complete them.

Please review my code and give some feedback about it. Thanks in advance.
