C++ free

Hello speps.
I tried importing xinput1_3.dll directly on XInputDotNetPure.

I confirmed it works on XInputDemo.exe and XInputReporter.exe including Guide Button but I don't use Unity, it's not tested on XInputUnity.
Because I can't judged whether XInputUnity needs XInputInterface, it's remained.

I also found an adjusting point on XInputDemo.exe.

P.S. I'm sorry for my strange English.
