logPackets is unused as well, but is still present in the config file.
Presumably got lost in the 1.7 update. @aidancbrady, should we reimplement

Move Config variables into their own class, (in api because other stuff in API references config, may make sense to move it back to common later), and move Blocks and Items into final variables in their own classes. It looks a lot cleaner this way and my OCD can finally rest now.
