Breaker fixes and map changes

Breaker boxes would not always place down all the cables necessary to connect power grids on server start.
Moving initialization from the New() to the initialize() appears to have resolved this.

Re-organizes maintenance areas, adds missing air alarms, lights and cameras to substations.
Re-adds a number of suddenly missing power cables, mainly affecting security.
Replaces a few instances of blood on the station with oil. Having round-start blood in secluded areas would get annoying fast..

Most of these things were intended for dev but with the recent merge I kind of had to move over to dev-freeze.
