* Tweak Fire Protect
This change tweaks the fire protection function so that it no longer needs to override nodes and hence rely on additional dependencies like ethereal mod.
* Remove ethereal and fire dependencies
Remove fire and ethereal dependencies as they are no longer needed since fire protection doesn't override items inside those mods.
* Re-add Torch Damage
This re-adds torch damage of 1 per second if fire protection is enabled.
* Remove nether dependency
Nether dependency isn't required as well.
Some armor was too powerful that killing yourself to respawn wouldn't work or instant kill tools for admin didn't have effect, so I've added a check so that if the player is dealt with more than -100 damage points it instantly kills them but doesn't damage armor. Also added /kill command.
sometimes dtime isn't registering when armor.update_armor is called and so it never checks for fire resistance on armor meaning cactus is fireproof if ethereal mod is found... we cant have that :) replaced dtime with ARMOR_UPDATE_TIME and it works fine :)
