Better Mob Combat

- Added new configs "mob_additional_upswing_multiplier" and "mob_begin_attack_range_multiplier" to help adjust the upswing speed and perceived attack range of mobs using Better Combat attacks.

- Added new config "mob_begin_attack_delay" to configure the delay prior to launching a Better Combat attack for mobs.

- Fixed Recruits holding a two-handed weapon being unable to eat. They will now store their two-handed weapon in their inventory, eat their food, and then re-equip the weapon once finished.

- Fixed a bug with parsing the "mob_relations" config if it contains entries for mobs that aren't present in a given modpack.

- Added support for CustomNPCs, Minecolonies, Modular Golems and Iron's Spells and Spellbooks (specifically for its unused WarlockAttackGoal).

- No longer requires Mob Player Animator to be present on servers.
