Radar Jamming Improvements

[VicViper]

Propose improvements to the radar jamming effect. Stealth actual unit while jamming is active, don't allow the fakes to rotate (this makes it too easy to get the accurate location via center of rotation), change the number of fakes to a random number from a set number, cause it to change/re-randomize the position of the fakes periodically (either one at a time by deleting the oldest fake and making a new one, or just all at once by toggling itself)

jamming appears to be implemented fully in the mohoengine and is thus in compiled c++ code that cannot be changed.
