feature: Npc Improvements - Dynamic Bosses

[Irokaiser]

Description

Boss battles are currently very stale where the npc just runs at you and spams spells off cooldown.

1. A list of Move Routes where routes can be disabled based on conditions i.e. Instance Variable = 2 or Health < 50%.
2. Spell Conditions - E.g. Can only cast this spell when Health < 10%, Instance variable > 9000 or move route completed.
3. Npc's to set Map Instance Variables on move route completion, health % or spell cast to trigger other map events.
4. Equipping projectiles to Npcs (instead of melee only attacks).
5. Configurable ranged option to enable NPC kiting so they try and keep their distance between the player at a 'sweet spot' being the range of their spell/projectile
6. Less Clunky movement. After each successful movement in the pathfinder we seem to wait arbitrarily 200ms before doing the next path finding route. Fairly sure we can remove this 200ms delay without any repercussions.

Intended Use-Case

This feature would be able to create more interesting fight scenes as opposed to the current wet noodle fights.
