PDA stuff for Seryder's future mapset stuff
Whoops, this wasn't ready yet
Fixed some menu overlap and entry bugs, also reduced the effect of luck on health bonus item drops
These really don't need to be here anymore
Vitality changes scale health, Purple Aura monsters heal others

- Whem monsters level-up, their health will scale from their previous value so
  that they have the same percentage of health as they did before they leveled
  up. That means that leveling will not particularly "heal" them anymore, but
  rather just scale their existing health up.
- Purple Auras now heal their teammates for 10% of their maximum health every
  time they themselves regenerate health. Added an effect for it, too.
Red Auras can Curse or Silence you if you are close and damage them

They will now Curse you if you damage them, or Silence you if you hit them with
an EP-based attack (currently Weaken or Soul Steal). The chance of it taking
effect is based on how close you are to them, and their base strength, making
melee-based and fast-moving monsters more dangerous with Red Auras.
Orange Auras love to teleport next to you if you're distanced from them
