2.16.2

- Adds a method to set mouse inputs as initial bindings
- Adds a way to set the initial bindings to nothing (good for when you want to make a keyboard input but don't have something on the gamepad for it)
- Fixed a bug where the control path and groups weren't being set properly on the bindings.
- Added `FlipImages` to `RebindingHelper`. Used for horizontal axes.

Should fix the bug where the new input binding OWML didn't work at all
