This PR internally rewrites MrBomb to be more like GoldBomb. It doesn't add any considerable features.
It also removes lots of code duplication. The Bomb class is now obsolete.
As a result, the death script stays consistent between MrBomb and GoldBomb.
This PR also fixes a bug with gold bomb, in which getting out of the safe distance and going back in would freeze gold bomb in the same sprite action until another state change.
