finishWounded-method created

I created a method to shoot nearby where we just hit. if it fails on
the first couple of tries, it still attempts to hit nearby the original
hit-location. if everything else fails, it returns to ‘search and
destroy’ mode. also if suddenly we successfully sunk a ship it also
returns to ‘search and destroy’ mode, instead of continuing shooting
nearby - that way we save some shots for our gain (points)..! :D
