Changed binary OR to logical one.

Calclavia, look at the code. I didn't understand what does that method do, and explain. That's why I changed "," to "||".
Update Vector3.java

Rewrite "rayTraceBlocks(this.toVec3(), vec.toVec3(), collisionFlag | !collisionFlag);" to "func_147447_a(this.toVec3(), vec.toVec3(), collisionFlag, !collisionFlag, false);" Thank fnuecke!
