-Added constructable solar arrays.

-Added a solar pack crate to order.
-Machines that have a use_power of 0 will no longer be turned off due to lack of power in the area.
-Fixed a bug with the solar computer not reconnecting to the powernet when dismantled and remantled.
-Increased the cap of crates to 30.
-Some performance tweaks.
-Some standardization.
-All objects of type /obj/machinery/power will try to disconnect from the powernet before deleting, this will help reduce the node list size.
-Added a heat_proof variable for doors. It will effect glass airlocks and it'll determine whether they can block heat or not. Research glass airlocks will always have it enabled.
