[store_unit_defense] tag

Browse source 
Stores in variable the defense of a unit on a particular terrain. If terrain is not specified, the terrain on which the units currently stands is used. (Note: it is a WML defense, so the higher it is, the weaker unit's defense is.)

* StandardUnitFilter
* loc_x, loc_y: x and y of terrain location.
* terrain: alternatively, the character of terrain.
* variable: the name of the variable into which to store the defense. default: "terrain_defense"
