Release notes:
- fix a bug when using multiple devices with FFB
- fix the RAM pool reporting in the FFB's PID block
- removed the FFB registry keys from the inf file to avoid vJoy to be always detected as a FFB device. On latest version of Windows (10), vJoy is normally seen as a FFB device even without the keys in the inf file. They are now provided separatly in .reg files (AddvJoyFFB.reg and RemvJoyFFB.reg) that you have to manually run if you need FFB and your OS does not detect it automatically.
- fix a few bugs in the C++ sample
- added FFB in the C# SDK sample.
Many thanks to Justin Shafer who spent many hours to sign the driver!
