Bomb Arrows for 2.55, v0.2

//Bomb Arrow Script for 2.55
//v0.2
//By ZoriaRPG
//19th March, 2019

//v0.1 : Initial
//v0.2 : Fix comppile, and fix how we check if the arrow is dead to create the explosion.
//     : We cannot run the explosion after while(this->isValid()), because the script runs out of scope if the
//     : sprite is no longer on the screen. Thus, we check its deadstate, while it is valid.
