- Removed DUMMY_INPUT. NC (not connected) pins should now use NC_PIN. If a NC_PIN is actually connected, an error will be logged and validation will fail. - Enabled "extended" validation. This will catch now if power terminals are not connected. - Added const and noexcept where appropriate. - Removed dead code. - Fixed the 7414 Schmitt-Trigger device to use nld_power_pins
