input: Allow repeat filtering to be disabled
Generally the input library handles processing of a list of scanned keys. Repeated keys need to be generated based on a timer in this case, since all that is provided is a list of keys current depressed. Keyboards which do their own scanning will resend codes when they want to inject a repeating key. Provide a function which tells the input library to accept repeating keys and not to try to second-guess the caller.
