[MIRROR] Improve atmos components code + OmegaStation fixes (#2752)

* Improve atmos components code + OmegaStation fixes

* Update circulator.dm

* Update dp_vent_pump.dm

* Update pump.dm

* Update volume_pump.dm

* Update pump.dm

* Update pump.dm

* Update volume_pump.dm

* fixes pumps shows area rather than vague jump

also removes it from admin log, wew
