AGI: Numeric Keypad Control in Predictive Dialog (Bug #3309376)

In AGI games, the numeric keypad is used as an alias for cursor keys to
allow stationary and 8 directional input, but while the predictive
dialog is open, this is more sensibly mapped to numeric input to
allow use of the predictive input on desktop ports.
