HALO problem and Domination Change

[br]

We finally found out that a system call for "onmapsingleclick" has been "depreciated" and that call must be done by a new method which is a real PITA. So instead I removed the HALO feature entirely, then changed the logic so that all targets are within 5.0 KM of the base to allow easy timely access by land vehicles or even on foot. Hope you all enjoy the revised version.
