Mob API: Merge mobs_mc and mcl_mobs into one mod

DO NOT USE IN PRODUCTION, DO NOT START OLD WORLDS WITHOUT A BACKUP
These are the first steps of the new mob API. The game does actually start, but mobs do not work yet.
You will also get some warnings about mob spawners, but don't worry about that.
This is really just some 'first impression' of how the mob API is gonna look like. Some things are already complete, like the agression system.
AI and attacking have not been worked on yet.
mobs_mc and mcl_mobs have actually been merged into one piece but I will probably change that again in the future actually, and split the different mobs into different mods.
There are also a few usefull things like the universal mount API and a more general purpose smoke API, but all of this is still far from complete.
I'll put some work into the API this week but probably not next week, then I'll see but don't expect this to be done before 2022.
I'll work on it, but I'll do it slowly and progressively to not get burned out again and to still have enough time to graduate from school in the meantime.

+This is a merged version of Mobs redo MineClone2 Edition (API) and mobs_mc (Mobs content).
+The API was rewritten by jordan4ibanez and later Fleckenstein from Mobs redo MineClone2 Edition and merged with mobs_mc by Fleckenstein.
+Mobs redo MineClone2 Edition was built by Wuzzy2 and contributors from Mobs Redo. Mobs redo was built by TenPlus1 from Simple Mobs by PilzAdam and mobs_mc was built by maikerumine.
+
+Seems like we've come a long way since 2012.

+Implementation of the Minecraft 1.16 Anger System (copied from https://www.minecraft.net/ru-ru/article/nether-update-java, with modifications):
+
+Forgive dead players
+
+    If this gamerule is disabled, then angered mobs will stay angry even if the targeted player dies
+    If both forgiveDeadPlayers and universalAnger are enabled, an angered neutral mob will stop being angry when their target dies. They won't seek any new targets after that
+
+Neutral mob anger
+
+    When hurt by a player, the neutral mob will target that player and try to kill it
+    The mob will stay angry until the player is dead or out of sight for a while
+    Anger is persistent, so a player can't escape by temporarily logging out or switching dimension
+    If a targeted player dies near the angered mob, it will stop being angry (unless forgiveDeadPlayers is disabled)
+    Neutral mobs also get angry at other mobs who hurt them. However, that anger is not persistent
+    Angered neutral mobs will only attack the offending player, not innocent bystanders
+    Some mobs spread anger (wolf, Zombie Pigman). If a player attacks one, all nearby mobs of the same type will get angry at that player
+
+Universal anger
+
+Universal anger is basically guilt by association. A neutral mob attacked by players will be angry at players in general, regardless of who attacked them. More specifically:
+
+    A neutral mob attacked by a player will target the nearest player, even if that player wasn't the attacker
+    Every time the neutral mob is hit by a player it will update its attack target to the nearest player
+    Players can use this to make neutral mobs attack other players. Who would ever do something that devious?
+    Universal anger does not apply when a neutral mob is attacked by another mob - only when it is attacked by a player
+    Universal anger is persistent. The angered mob will stay angry even if the player logs out and logs in, or jumps through a portal and back
+    mcl_mobs.mobs that spread anger will also spread universal anger. So if a player attacks a Zombie Pigman, all other Zombie Pigmen within sight will be universally angry and attack their nearest player
+    An angered neutral mob will stop being angry if it can't see any eligible target for a while
