Couple of bugfixes:

Wizards can no longer cast spells when muzzled. Fixes issue 843.

You can no longer take bags of holding or mechs to the clown planet. Fixes issue 1061.

Removed the infared sensor from the autolathe construct list. Fixes issue 1092.
- The infared sensor already does nothing, the code for it seems to have been removed ages ago, so there's no harm in doing this.
- Commenting out the define caused a few problems that I couldn't quite figure out. I'll leave it for now with a warning.

Removed the ability for pAI's to set arrest status. Dead players really shouldn't be allowed to grief people like that. Fixes issue 1093.
