Remove Hygiene Motive from RP

[Wisemonster]

I will add to this, that a Devera board interdictor (the one that reduces miasma) will prevent passive hygiene decay for any mobs under it's influence. So you could ask an engineer to build one in the location you want if you don't like having to clean yourself so often from the passive decay. Though these interdictors are usually only built next to the cloner, if they are made at all. It also doesn't prevent decay from things like getting covered in blood.
