Fixed game crashing when the active creature dies
requested to merge github/fork/iBlackShadow/iblacksahdow/fix-game-crashing-when-active-creature-dies into master
Fixes #1416 (closed)
the problem was that when a creature dies his health indicator its destroyed(Line 1625 on creature.js) but later on the game tries to update the health of the last creature that move which is the dead creature so the game crashed.
