0.3.1
    - Fixed position bug with the "spawn" function when using tags.
    - Default for "set_block" update is now 3 instead of 2.
0.3.0
    - Drops functions called in stats are now themselves saved and executed on death.
      - Old individual item and entity lists will still be dropped/spawned, but no longer created.
      - This means ALL drops functions can now be used exactly as if they were in the drops section.
    - The nbt function "compound" now only overrides the tags defined in the function, instead of the entire compound.
    - New life cycle event - "pre_stats".
    - New universal function - "external".
    - New drops function - "set_block".
    - New nbt function - "chest_loot".
    - New conditional checks - check_nbt_X, above_looting_X, raining, thundering, moon_phase_X, beyond_X, past_world_difficulty_X, player_online_X.
0.2.1
    - Reimplemented MobProperties.json (the main default property file).
    - Now will print warnings when using numerical item/block ids (should still work for now, though).
    - Now accepts peaceful/easy/normal/hard in addition to the numerical difficulty ids for difficulty_X conditional.
0.2
    - Uses a new verification system!
      - Makes sure you are defining all required fields.
      - Makes sure you are only using valid fields or "_comment".
    - Made more fields required (some optional fields had defaults that made the entire function do nothing).
    - New conditional checks - difficulty_X, in_biome_X, on_block_X, past_day_time_X, past_world_time_X.
0.1
    - Bumped up to beta.
    - Mob property files are now parsed in JSON format!
    - Mob id is no longer based on the file name (compatibility fix).
    - New command to reload properties - /mpreload (must be in SP or be an OP to use).
    - Item drops can now be modified by a mob's stats.
      - All drops functions can now be called in the stats function "drops", except "default".
    - New conditional checks - burning, wet, wither_skeleton, in_dimension_X, below_X, has_potion_X, and killed_by_X.
    - Potions can now be applied to potion-immune mobs and/or marked as ambient ("override", "ambient").
    - Mobs' base attributes can now be set using the "modifier" function's new "override" field.
    - New stats functions - "drops", "nbt".
    - New drops functions - "spawn", "xp".
    - MobProperties.mob/json was removed temporarily.
    - Probably some other stuff I forgot.
