Completely rewrote the input binding system
- All inputs can be bound to key / mouse / joy
- Multiple keys can be bound to the same action
- You can now cycle between 3 separate input binding profiles
  - Settable in key binding menu & with a key in the dsda section
- You can unbind joy buttons
- Random system keys like “volume up” shouldn’t cause random effects (at least it is fixed for me)
- More joy buttons can be configured
- The key binding configuration format has changed…you’ll need to rebind your keys
