Separated DirectX content from:
1) dll entry functions 2) Server (inside the dll) 3) Server-Client interface. uMod now detects if a DirectX device was created and is under "control" of uMod (a counter is shown after the game name). Thus if the injection did not work properly, uMod wont show a DX9 or DX9EX count.
