Improve Dodging and reactions (#422)

* Improve Dodging and reactions

Take advantage of new getUnitState command

Fix some cases of units warping through cover
Improve Dodge and Cover conditions. Units are more likely to drop prone and appear suppressed if under heavy fire.

* Update fnc_doCover.sqf

Removed #define. It didn't improve readability in any way.
