Freeze mouse cursor in-game

[DrChat]

While in-game, the mouse cursor is merely hidden and confined to the bounds of the window rather than frozen in the center of the screen.

Combined with the Windows 10 game overlay, this means that the mouse cursor can interact with widgets, and any interactions with widgets will suppress input (in most cases being mouse clicks to fire weapons).

See if there's an easy way to freeze the mouse cursor in place. It'd likely be the same place where the mouse cursor is hidden.
In addition, determine if it's appropriate to apply a fix in this hook, or if fixing this behavior via UnrealScript would be better.
