Add event "flag_change"

[Kappa-131st]

It would be interesting to add an event concerning the radios menu : 

flag_change

Event = {
 id = xxxxx,
 idx = number markId,
 time = Abs time,
 initiator = Unit
}

this will allow you to know precisely the unit (player) that launched the trigger via the radio menu.
Thus, one can imagine programming a personalized radio response for the unit that triggered the flag (For example, a response containing a heading, to follow, a distance to travel for the unit that requested, calculed from the position of the initiator, or containing the name of the initiator (Even if the triggers are active for the whole coalition/group)

Currently, we cannot know the initiator of the triggering of a custom radio menu. The flag is triggered regardless of its initiator

This is possible with scripting fairly easily. Drop me a DM if you need some pointers.
