Fixed an issue with respawning bosses causing them to not actually respawn when killed.

Further you can now use the following placeholders in commands which are executed on boss death and the killedMessage of each boss!


# <mostDamage> to input the player which did the most damage to the boss which died.
# <killedName> to input the Dead Bosses name. This should not be necessary often, but is possible. (possibly necessary to name items or put text in a book or so?)
