Subs would now have the ability to ping. What it would do:
-send a ping out in a circle around the submarine (diameter of the circle is based on
sonarman's ability)
-any ship within this circle now has the fog of war shadow for 5 seconds.
-B.O.'s will be able to detect this ping based on how close they are to the sub and
the B.O.'s potential (i.e. The B.O. allows the ship to detect pings within a circle
around the ship. Better potential = bigger circle)

Pros:
-Helps scout for the whole team, whenever used
-Can detect CVs that have strayed too close to the front lines

Cons:
-Give away the sub's position
-Doesn't really help the sub, unless it is submerged late game and has no idea
where to go with limited air

Best used when SS has engaged its first BB. This will allow the sub to get a clean kill,
but also allow it to scout for its team.

The whole purpose of pinging is to help improve scouting for BBs. Some may claim it
buffs subs, but I think it hurts them more than it helps them.

Future Suggestion if this gets popular: Dummy ping buoys

Just to clarify: the ping goes past normal sight range for submerged SS. Other ships
only detect the circle from a ping; giving other ships the ability to ping would result in
SS becoming obsolete.
