Chaplain PDA Bug Fix & Atmos Dedupe

- Chaplain PDA bug: Caused by the chaplain custom preview calling equip. Disabling it seems to have no issues with the preview and stops it making a new PDA every time it generates a new preview.

- Atmos Tech Dedupe: All engineers start with a T-Ray in their right pocket. Atmos techs also had one in their toolbelts. And now the extra one in the toolbelts is gone.
