dinput8 Dll(Un)RegisterServer

[Kovács András]

Hi,

I implemented (taken from wine's dinput directory, modified) dinput8's 
DllRegisterServer, and DllUnRegisterServer functions, which will register 
dinput8, and dinputdevice8 co-classes.
With this patch Tomb Raider Legends go further, then crashes again with 
builtin dinput.
Applies to current cvs.

Changelog:
* Implement Dll(Un)RegisterServer
