fix of add vector to current velocity
Merge remote-tracking branch 'origin/konkitWorkingBranch' into Zyga_Working_Branch
Added Collision between all type of objects. If there is collision between two ships, they are die. If is collision with Static, colliding object die, and static receive damages depends on ship velocity, If is collision with explosion, the amount of damage depends on size of shockwave (explosion is strongest when shockwave is small)
