bomb: learning godot by creating something like atomic bomberman in 3d

Done

• Added check if something is in the way of the explosion

• Add better check for explosion collision (take explosion size and correct mask) -> Explosion blocker like blocking tiles

• Add check for destroyed objects in explosion using different mask and shapecast -> Destoryed objects like players, other bombs and some tiles

Next

• Bombs explode when caught in explosion
• Create random bricks

Move around with W/A/S/D and drob bombs with space
