improved enemy - player collision and combat code

ran into a humorous bug where the enemy seems to be trying to suffocate
the player, may consider incorporating into the game
partialy fixed the bug

attack collision on the lefthandside is finicky and when the player and
the enemy colide the player gets turned around
added enemy health and made CheckRange only occure once per press of square
added the samurai images under assets

cant get any animations that i add to work
put in samurai run
