Some more Stealth changes.

(1) Use diminishing returns for passive training depending on skill level.
    Below skill level 2, chances are unchanged; at level 2 chances are 2/3
    of that, and at level 3 at 1/3. From level 4 onwards, Stealth cannot be 
    trained by waiting anymore.
    
(2) Active stealth training only has a 1% chance (instead of 5%) if you're
    sneaking around monsters while invisible (and the monster cannot see you).

Add yet another function for blood potions - I sure hope this works when I 
eventually get around to actually use them.
