NG patch 24 debounce in 10Hz timer not on port ISR -- 6824/382/38/128 build size

[Simon Jackson]

Using a port state change for key debounce is a bad idea. All to avoid a 10Hz interrupt. This way does have the advantage of not suffering from port crackle IRQ bit toggling. Even though this can be eliminated from passing a duration check, this check would only be available with 10Hz running. So if you live in a noisy environment, your device is going to be less stressed by key ISR crackle.
