So just discovered that the DreamSMP allows spawners and cake to be silk touched.
So in light of that I have enabled spawners to be picked up (but they always turn into pig spawners)
Also have allowed cake to be picked up. but it is now under a config option. If you had 1.0.0 installed prior you should delete your config.yml and let it regenerate or you can add the new config option yourself by looking at the example
