The .INF is compiled into the DLL as a resource.  Packagers shipping
binaries won't have to do anything different.  It simply makes editting
the registry keys much easier and less error prone.  Also, Roy obviously
put a lot of work into doing it the nice way, so I feel bad ripping it
out and hardcoding everything which just makes the code uglier anyway.

The .INF is not loaded from a path, it's loaded from the HINSTANCE of
the DLL, which is provided to the DLL in DllMain.

I admit this isn't exactly the way Windows does it because the registry
entries appear to be in the initialized data section of the Windows DLL,
but then again, we don't have to maintain the Windows DLL.
