Use SDL Game Controllers API

• Remap the existing joystick usage over the game controllers API
• Restore default LT and RT as Use Item and Drift
• Map SDL controller dpad as hat
• Bump execversion to 10
• Migrate the previous Xbox DInput default mappings to SDL Game Controllers
  • This migration is only performed if the binds are unchanged from the defaults in 1.5, and done on a per button/axis basis.
