Two Forks VR 0.0.7

• Redid how the input bindings work. This should prevent problems with conflicting inputs, like when moving the right joystick would also trigger the action to drop items held in hand. This might also break some other input-related stuff that I haven't tested yet (maybe some buttons are missing). Please let me know if you face any issues.
• Force game to detect a controller, which causes the UI to show Xbox icons instead of mouse/keyboard ones. This still won't show your actual VR controller buttons, but it's closer.
• Add a temporary binding to put held items in the backpack using the "Jog" button. Also the same binding used for eating held items. Temporary because I'll make this a gesture instead of a button.
