Title: Allow getBlock compatibility with old maps

getBlock doesn't accept default IDs < 256 which will break old maps unless the user backed up the old configs as well, which is obviously not happening often enough and causes some major support overhead.

It's not suitable for us to change the default IDs until a sufficiently long migration time with working ID checking between world and config passed. The lack of RP2 updates caused users to stay on 1.2.5 until now.
