* Added ZONE_OVAL. This can be useful for simulating the area of a view zone from an object looking down at the ground for example.
Can be constructed from a Mission Editor drawing.
* add to DB
Supports closed line segments, rects and freely drawn polygons.
Added the correct way of generating a point within a polygon with trial and error
Added a way to get the surface area.
Added a helper class (_ZONE_TRIANGLE), which shouldn't ever be used on its own. It's there to support the update ZONE_POLYGON.
Some test code, assuming there's a poygon drawn in the mission editor called "poly":
```Lua
-- make a new zone from a drawing
poly = ZONE_POLYGON:NewFromDrawing("poly")
-- draw the zone for everyone, include the individual triangles that make up the polygon
poly:DrawZone(-1, {1,0,0}, 1, {1,0,0}, 255, 4, false, true)
-- generate 500 random points, evenly distributed in the polygon
for i=1, 500 do
COORDINATE:NewFromVec2(poly:GetRandomVec2()):CircleToAll(1000)
end
-- remove the drawing from the game
poly:UndrawZone()
```
*Link16 fixes
* Wrongly created STN's will be replaced with random five digit octals with leading 0
* Voice call sign label will be the callsign's first and last letters, e.g. Enfield = ED. Navy One = NY
* Voice call sign number equals callsign minor major, e.g. Enfield 6-1 = ED 61
* Also works for A10CII which has a different entry with a four-digit octal with leading 0
* for fighter aircraft you can use :InitRandomizeCallsign() to give each spawn a random callsign
