Submarine Squad: Sounds and attack mechanics development

Added basic sound effects: 

- movement and rotation of submarines
- grabbing resources from the bottom of the sea
- launching and hitting a torpedo menu buttons 

Added music for the main menu

Work is underway to improve the mechanics of torpedo attack:
- the torpedo can be launched if the enemy is in the field of view (+ - 90 degrees relative to your submarine)
- the torpedo is fired one step away from you in a forward direction, then it searches for the enemy and goes to him along the intended path. Thanks to this, the launch can be carried out from shelters.
