JBOF: Just a Bunch of Fixes (#3957)

- Renames orphancompiler.py script to propscheck.py, the name fits better - Fixes Go props to make them easier to maintain - Alphabetically sorts some listings in the code - Adds tests to the props checker script (No idea how to integrate those so it's manual for now) - Adds 2 missing limit cases for Motd filtering
