* Modfied frontline vector to ensure start point stays outside of
exclusion zone. (Previously it could be up to 100m inside)
* Change randomization in offset distance from frontline to be based
on a percentage of the unit type's fixed offset instead of the
width of frontline.
(Prevents units from being far from their expected distance from
frontline)
* Change visualgen to use the same frontline vector calculation as the
unit spawns
* Prevent common cases where ground units do not spawn due to
frontline position being in exclusion zone
* Fix case where ground units will spawn inside exclusion zone due to
random offset from frontline center being fixed
* Remove dead code from `conflictgen.py`
* Start cleanup of `GroundConflictGenerator`
The AI isn't making use of these yet, but it's not smart enough to do so
anyway.
Would benefit from an icon to differentiate it on the map.
I'm stretching the definition of "control point" quite a bit. We might
want to put a class above `ControlPoint` for `AirSpawnLocation` to
represent types of spawn locations that can't be captured and don't have
ground objectives.

Somehow this constant was wrong so all of our foot-to-meter
conversions were coming out ~7% too large. We're still introducing
some error because we're rounding early rather than only when we need
an integer, but it's much more accurate now.
