This does not work with WorldGuard, and will allow creepers to (temporarily) damage WorldGuard regions!

Protects your server against Creepers, TNT, and griefers!

CreeperHeal is more than a griefing protection plugin : it repairs the damage done by explosions (Creepers, TNT, etc...) and fire, in a natural way! Stay a while after a Creeper made a hole, and you will see the terrain pop back slowly, block per block, exactly as it was before the explosion! That way, your players will still be afraid of Creepers, but your server will continue looking nice!

Anti-Griefing features
Natural healing of the terrain after an explosion
Fully customisable

log-level : (0 - 3) Amount of debugging messages shown. 1 is recommended.
op-permissions : OP have all permissions.
crack-bricks : (true or false) Whether bricks destroyed should be replaced as cracked ones.

- Ghast : (true or false) same for ghast fireballs

- Magical : (true or false) same for explosions from other sources (other plugins?)
    - Fire : (true or false) replace damage done by fire

- restrict-blocks : (false, whitelist or blacklist) Set to false to replace all blocks, whitelist to replace only the blocks defined in the whitelist, or blacklist to ignore those defined in the blacklist.

- restrict-list : (list of block ID separated by commas) whitelist (or blacklist, depending on the setting above)

------------------------------------------------------
TRAPS
------------------------------------------------------

Traps are TNT blocks that are automatically replaced along with their explosion's damage. Thus, the trap is reset. It allows for hidden TNT behind a wall, or pressure plates under the snow... Feel free to experiment!

1. Set up a trap.

Set a TNT block wherever you want. Look at it and type "/ch trap create". You should have sufficient permission for that (either of those nodes : CreeperHeal.* CreeperHeal.trap.* CreeperHeal.trap.create). Now, whenever this block explodes, it will pop back along with the rest of the blocks destroyed. And it is protected from getting destroyed by angry players!

2. Remove a trap.

If you are the owner of a trap, it's simple. Either look at it and type "/ch trap remove" or simply destroy it! You should of course have at least the node CreeperHeal.trap.remove.own, or CreeperHeal.trap.remove.all, or any of the wildcard (*) nodes.
If you're not the owner of the block, same procedure, but not the same permissions. This time you HAVE to have CreeperHeal.trap.remove.all, or any of the wildcard nodes.
