[ PvE ] - Boss Run

I seperated the Boss element from the other mode.
Generate bosses to fight based randomly selected status ability, hero, movement ability, and special ability.
The boss tracks player movement better than previous modes. I change the AoE indicators.

Optional (Turning off helps the game run better)
After starting a reload, if you time pressing the reload button you get extra damage.
Double tapping a s w d keys in any direction with make you dodge in the direction you tapped.
