Complete the implementation of ECM (Electronic Counter Measures) in the code. 

This is still a preliminary implementation, but works. If a source object tries
to see a target object whose ECM power is higher than the source object's sensor
power, the source sensor range is reduced by one third. Cyborgs get an innate
ECM power bonus, and enemies now need to be one third closer to hit them.
