It'd be nice to have a way to get the load percentage of a reactor - that is, how close the reactor is to overloading.

With access to this information, devices can disable themselves if the ship's reactor is close to overloading.

Fixed in 1.7 Alpha 2.

I've added a property on ships, 'powerUse, which returns the number of kilowatts of power currently being consumed. This only works for player ships (all other ships return 0). The value is returned in a double (floating-point) so we can handle future, large reactors.
