* drawing of nametags is now it's own function defined in cfgFunctions
* added optional display of unit group (using groupID)
* optional information (distance, type of vehicle) is now played beneath name, slightly smaller
* units in cargo never display type of vehicle to avoid clutter
* removed code remnant
* Added briefing section for group names
* Declared private variables

BUG:
suffix sometimes applies to unit in cargo slot - why?
* moved colorization to function
* fixed false-suffix bug
* more comments
