Changes Proposed

These changes are inspired by the PR linked as Based.
Basically, this PR adds the possibility of partially enabling the bestiary system, more information needs to be added, but this is a good starting point.

The MonsterType function now also accepts a raceId to obtain the MonsterType linked to that raceId.
New function Game.getBestiary() that returns a table with other tables containing name and list of MonsterTypes, both compatible with the Lua # operator.
Compatible with Revscript.

Based: #4356

After killing some Dragon Lords using bestiaryPointsPerKill = 100 the client is crashing and returning the following console error:

Oops sorry, I forgot not all elements are counted here, I'll fix this in a bit, thanks for reminding me <3

Okay, no errors were returned in any of the bestiary steps and no crash occurred to me.

However I encountered a problem when killing a monster in a party:

Lua Script Error: [Scripts Interface]
D:\Repositorios Git\forgottenserver\data\scripts\creaturescripts\bestiary_kills.lua:callback
...enserver\data\scripts\creaturescripts\bestiary_kills.lua:18: attempt to perform arithmetic on local 'killers' (a table value)

• All bestiary steps work as I expect;
• The description works as expected;
• bestiaryPointsPerKill works as expected;
• bestiaryPartyKillSharing works as expected in both scenarios.

On the client side everything is as it should, I believe it can be merged as it is. If there is no change suggested by any staff member.

Thanks Arthur and Sarah for the content.

The points will no longer be counted twice for those who inflict damage to the monsters and are in the same group.
The behavior without sharing in the party was also fixed, which basically means giving the point to everyone who participated in the monster's death.
