Build 10479576

- Fixed the bug where opening the Esc Menu while the death animation is playing causes you not to be able to move in the next runs
- Holy boss added to the pool of possible bosses for the normal mode
- Fixed the bug where the Arcane Trap was not affected by the game volume settings
- Optimised the UI
- Option added to change the dash to "SPACE" Key
- Killing the boss removes all of its projectiles (e.g. End Boss slow-moving ball of death will be removed when he dies)
- Boss and Arena rooms are now considered cleared when the RuneKey reward is collected.
- Boss Rush mode rework, now gives you the option to choose 1 trap and 1 arrow ability from a pool of all unlocked abilities (finding the trap/arrow in the world unlocks the option)
- Added an in-game Timer which can be enabled in the options. The timer stops when going between rooms and portals, which should give a more accurate timing of the run for those who wish to speed run the game.
