After long periods of arguing with the developers to update the guide on the wiki and pestering people on IRC for help, I have managed to pull together a mod. It isn't too fancy, as I am still learning to code for The Powder Toy.
Special Thanks to:
Merbo - for helping me make DYNA and tweak a few other things
CONTENT
HETR - Heats stuff DYNA - Far more powerful than C-4 BOMB - tweaked to explode more violently

I can only compile for windows, so sorry Linux and Mac users
@RedFlash devast8a is right. He's not just being a meanie. TPT is under GNU license meaning that it MUST be open-source. Also, I helped you with everything in your mod so far, except for the BOMB tweak that you noticed could happen: pv[y/CELL][x/CELL] = * * was changed from 0.1f to 5.0f
