Extinguish TNT if below water #129

If an ignited TNT is directly below a water node, it should be extinguished again.

But rain should be ignored because it would be too annoying. Let's say the raindroplets just always miss the fuse. ;-)

I imagine a get_node call could be made every so often in the TNT's on_step? Haven't checked if TNT goes inside of another like in Minecraft though... Need to check out how it works

This would somewhat conflict with the ideas had in #69

Done. A burning TNT is now extinguished when it is about to blow up and directly below any water node. Attempts to ignite TNT below water will also fail.

Don’t worry, this doesn’t create any performance problems as the check is done rarely. TNT is always a node in Repixture, there are no TNT entities.
