Ghouls Can Clean And Haul

XML change that adjusts ghouls.

Basically re-adds worker to them but then marks all the various work/skill types as disabled.
This will allow ghouls to be picked up by the job giver and thus do cleaning and hauling.

You can't adjust them via the work tab as they aren't normal colonists and that would require C# to do, but given they can't do anything else (besides meleeing things) I feel like that doesn't matter too much.

Got this because I got awarded a Ghoul via Winston waves and I've just been stuck going "Wtf do i do with this?" As i'm not really much into using ghouls, so I figured i'd make them a little more of a passive helper instead of a thing that stands around and eats meat.

Known Bug

Ghouls will attempt to chop down a tree if you make a blueprint for a wall (or something else) over it. This is sort of a basegame bug/quirk. Pawn wants to deliver materials, tree is in the way, so they will go chop it so they can deliver. Not much can be done about this without a harmony patch, but this feels like enough of an edge case it shouldn't matter (not to mention they're gonna be bad at it so its not like its overpowered).

If added to an existing save! The only fix i know is to go into dev mode and "set faction" to literally any faction, then set it back to your faction.
This calls a reinitialize value that will set those priorities back to "3" in the background like a real pawn. As we can't access the work priorities for a ghoul this is the only workaround.
