Add support for hardware copy protection dongles in game i/o socket (#1153, PR #1154)

Changes:
- Add a drop-down menu to the 'Advanced' tab that lets the user select a dongle in use
- Add a new file "CopyProtectionDongles.cpp" that is a place to put drivers for these.
- Add a driver for the one known dongle we have now - Speed Star
- Modify Joystick.cpp to allow PB0-PB2 to be "pushed" by the protection dongle.
