Movement by holding arrow keys in U6

[Peppersawce]

Unlike in the original game (checked in DosBox), no possible setting in Nuvie allows for moving in a direction by just holding the respective arrow or numpad key, they have to be repeatedly pressed.

I assume at the very least the non-enhanced preset is supposed to be faithful to the original in this usecase, but in general I miss this feature of the original because it makes playing with a mixed mouse+keyboard setup a lot less cumbersome and more enjoyable for me, so I hope somebody could look into this :)
