* limit atmos/fire alerts to the current z_level

* atmos/fire alerts are now linked to an object and not its area, as intended
* simplified and full pathed the radio frequency datum
* made radio objects properly clean on del/qdel, instead of letting the radio controller remove nulls at each post_signal()
