Implementation of SCARD_IOCTL_LOCATECARDSBYATRA & Modification to make Smartcard reader with PinPad work

@awakecoding Beware ! 
I commented out this portion of code because for me it broke Windows smartcard login authentication. Surely It will break other applications from what you said in your note.

Actually, I done my testing in that environment : 
Windows Client -> Thinlinc (Ubuntu 14.04) -> Remote Windows 
So in my case, I think it's WinScard speaking to WInscard.

I'll check tonight if my modifications breaks application compatibility with this environment : 
Linux Client -> Thinlinc -> Remote Windows 
and
Linux Client -> Remote Windows
I'll keep you posted.

In the mean time, maybe it'll be safer to revert back this commit ?
