Added Knockback

Hi everyone!

So the player has both magic attacks as well as melee weapons. When you attack with the melee weapon I added a knockback to the enemy now. I think it looks a bit more realistic now:) There will be a hit effect as well and combat text but I will add that a bit later. I added a slight delay to the knockback and might have to reduce that a bit still.

I'm not sure yet if I should add this to spell attacks or just have the enemy be stunned. Thinking about this! There will be a freeze spell later as well so I have to think about this. 

Just a small update but no worries more to come soon!

Thank you.
