- Committed SuperSayu's patch fix for silicon alarms.

- Made the singularity not move stuff while contained, should help and make it easier to work with; such as fixing the field generator.
 - Added logging for gold slime extracts.
 - Removed unneeded deletion of signals in telecomms code.
 - Added a debug verb which will record pointers of signals that weren't garbage collected.
 - Removed the need to create a mob to compare it in telecomms code.
 - The spider infestation is more likely going to spawn nurses.
 - Runtime fix with spells. 
 - Reverse list actually does something now. Bots never needed it so I removed it. (Thanks carn)
 - Added an ON_BORDER flag for border firedoors.
