Fixes Cargo-ordered PAs and Wrenching-down Machines in Powered/DePowered Areas

Particle Accelerators will now update with current powernet information
upon being wrenched, just like all other machines. Fixes a bug where PAs
ordered from cargo would never detect parts.

Fixes a bug where machines taken from a depowered area and wrenched into
a powered area wouldn't be powered until you flicked the lights on and
off (or something to that effect).
