Minor Patch and Damage Update

New features :

- Your submarine has health-points now (7)

-It takes damages when you collide with reefs or go down on a reef using your ballasts dangerously

-The amount of damage depends of your speed

You can see the damages inside the submarine  by the number of breaches. For now you can repair a breach by clicking-it when you're very close.

Fixes :

-The clock stops automatically when it reach 60' instead of spinning infinitely with crazy numbers

-The multi-directional sonar button no longer flips when you use the one direction sonar (with B) 

-The submarine return to his initial direction when you get out of the "inside mode" instead of keeping a 90° position
