Vampiric Regeneration 2: The Actuallytestening

A fix for the coffin not actually fixing organs. Right now, it is pretty potent, if less so than ling regen - it regenerates all damages per tick,  plus has a chance to fix all organs (up to and including regrowing) along with a message to inform the player it's happened (I tested it, it's rare enough not to be a constant message spam, but as rare that it does not trigger at least once per a sleeping session.

You could tweak the values for balance, but coffin regen is very risky - it requires using a particular, conspicuous structure and being helplessly exposed to attack by anyone who finds it, and it immediately arouses suspicion when one is seen using/dragging one around.

However, it does *NOT* fix bloodloss, which I reckon makes sense - the last thing you want to happen to you as a vampire is to lose blood.
