Another "patch" for the purpose of giving Niina a new mechanic: the stance mechanic, since her last mechanic was either too limiting or overpowered.

The changes include the following:
 * Basic stats (health, attack, spell, difficulty) recorrected.
 * Ability style changed to Stance style. Abilities adjusted as so.
 * Fire Dance receives back its armor bonus, which has been reduced/nerfed.
 * Clown's persistent effect returns the 5-second taunt on non-champions but removes taunting on champions. The movement speed bonus also has been reduced to a 2.5 seconds duration.
 * Stun on Clown's active affects once every 10 seconds, not once per activation.

Well, I presume this will be the last revision for now, until later on...
