QoL improvements and Item tweaks

Based on user feedback, many of the debuff abilities automatically apply to the target right in front of you. Soon all hostile abilities might work that way, but for now it's just debuffs.

Dash now does damage to the mob you run into, the further the more damage!

Helm of Saving now only saves others, gotta use those potions (for now...)!

Eruption's knock back also faces mobs away from you. Great for getting extra damage on back attacks!

Also fixed a bug that could cause some ability buttons to not work if you left the game while holding shift. Random, but annoying!
