powerup descriptions
additional notes
- is affected by filter blocks (because i thought it would be funny)
- doesn't care about powerup tiers. any powerup it eats will override what it previously had (pretty sure this is accurate to its behavior in the source game)
- doesn't eat friendly powerups
- doesn't eat anything if it is itself friendly
- powers down if it eats a poison mushroom (can be disabled using the npc config "nopoison")
- has a per-instance setting in the editor if you wish to have it spawn with a specific powerup
