Make Reinforced Cobblestone harder to break for enemy team

Make it so that Reinforced Cobblestone is easier to break for the team that placed it but harder to break for other teams.

This works? Feels a little hacky. It might be better to make all reinforced cobble the hardened version, but have enemies dig it twice by replacing it with a second version of itself one dug by an enemy that has a cracked texture applied. Node dig predictions should be considered with that approach

A bit hacky, but works very well. I'd rather stick to this approach unless there's some unforeseen problem that might cause issues. Currently it is not complete though.

How does this work with internet lag? You might be able to simulate it with minetest.after()

The typical internet lag doesn't seem to affect it much. Bad internet lag (1+ seconds) makes it seem like it is dug "twice by replacing it with a second version of itself once dug by an enemy".

I suspect something is going to turn up requiring a change, but I'll go with it as-is for now
