 * Consider renaming externally visible variables, functions, and inventory
   items to include prefix of "ez_" in order to prevent conflicts and
   ambiguity when other mods interact with this one.
 * Avoid use of Thing_ChangeTID, since it makes this mod less likely to be
   compatible with other mods
 * When deathCrawl is enabled and a player is downed, ideally there would be a
   more intuitive visual effect like the player crawling with visible wounds,
   blood leaking, etc. However, this needs to be done in a way that is
   compatible with custom skins, models, and player sound effects. Fortunately,
   the player currently does the (mod-customizable) pain effect every second,
   due to ez_bleedFactor
