[CLOSED PR] Remove the Loafer

[zjdtmkhzt]

I think this is a great PR and I am all for this. The loaf jokes were funny for a bit, but they have long since run their course, and this feature only incentivizes mechanics into building big lag machines instead of more interesting contraptions.

Loaves don't really serve any purpose, and the uses they do have are blatantly imbalanced or clunky, and also unintuitive for new players.

I believe that with this removal we could free up some more design space on maps, for instance for a pathology lab.
