Map effects modificators

[Vladislav Belov]

It would be useful to have effect modificator, in example:

1. if an unit stays on lava, he gets damage.
2. if an unit walks through swamps, he has less speed.
3. if an unit walks through sandstorm, he has less radius of view.

So it could added like terrain painting or adding entity with editable form (like auras, but with different shapes).

Some mods yet do that in a hacky way (using farmland entity with an aura as you described). We can also think to forest giving a penalty / bonus (Iberian guerilla for example) but with auras, it would perf killer.

By the way perhaps this ticket is a duplicate of #3997
