WORLDGUARD-2452 - Reported by The_One

Hi.
I would like to make canons and others things but I only want player damage. So I disabled TNT block damage but now TNT cannot launch other TNT blocks when it explodes.

My feature request is simple, it would be very useful to have a whitelist for the blocks that TNT could damage (like other TNT blocks) even if block damage is disabled.
I know I could make some regions with block damage allowed but it isn't practical, players would have to wait for an admin to make TNT stuff.

That's all, thanks for reading. Sorry if I made spelling mistakes, english isn't my first language.
The One.
