Sounds/GameOver

Added Elf Sounds folder under Audio folder. ElfControllerScript(attached
to elf prefab) has 2 audio array variables. One for death sounds, other
for battle cries.  Wrote 2 functions trying to randomize the playing of
these clips.  Then calling the death sound functions in the collision
scripts.  Will randomly play battlecries as the elves spawn using that
function.  Currently not working though, I think I'm doing something
wrong with the range in the functions.  After this small thing is
figured out, just add a game over screen that lets you restart after
health gets to zero and commit so I can post.  I'd like the punching to
be a little easier to do, but if not its ok.  3 days late isnt THAT
bad....I guess.  Bawls.
