MrMelbert aea1b5cf14 Adds a new heretic path: Path of the Blades (#65718) 
This PR adds a new heretic path.

The Path of the Blade, a path focused on becoming a powerful one-on-one combatant with your blades.

Main path:

Cutting Edge: Allows them to transmute up to five knives. Knives are made with two bars of silver.
Grasp of the Blade: The Mansus Grasp will stun and deal additional damage to people lying down or facing away from you.
Dance of the Brand: Being attacked while wielding a blade will cause you to counter-attack whoever hit you.
Mark of the Blade: Marked targets will be unable to exit their current area. Triggering the mark will give you a floating knife which will block the next attack you receive.
Stance of the Scarred Duelist: Blood wounds inflicted upon you are reduced in severity greatly, and you gain immunity to dismemberment. Dropping below 50% health will grant you stun resistance and wound resistance.
Swift Blades: Wielding a heretic blade in both hands will attack with both at once. The second attack has a small damage penalty.
Furious Steel: A spell that grants you three orbiting blades. Each blade will block an attack upon you, and you can fire the blades at people for decent damage and bleeding.
Maelstrom of Silver: Ascension ritual, surrounds you in a whirlwind of eight blades which block attacks. These regenerate over time. Heretic blades deal massively increased damage and offer lifesteal, and you become immune to stuns and wounds.
Side paths:

Void / blade 1: Shattered Risen. A summon like the voiceless dead, shattered risen are tankier and deal immense damage with their fists, especially to structures, but cannot hold items.
Void / blade 3: Maid in the Mirror. A summon that can jaunt infinitely around the station. They can only enter and exit the jaunt around reflective surfaces, such as mirrors, windows, titanium walls, or reflective armor.
Rust / blade 3: Lionhunter's rifle. A three shot rifle. When fired at a non-living or close range target, it fires like a normal weapon, however clicking on distant targets will aim at them. The projectile shot at aimed targets deal massively increased damage and cause stuns / knockdowns. It will also track them and travel through walls.
Rust / blade 3+1: Additional ammo for the lionhunter's rifle.
Other side path changes:

Blood Siphon is now a t2 side path, between Flesh and Void.
Cleave has been moved to between Flesh and Void
Rusted Ritual has been moved to beween ash and rust
Also refactors heretic paths a great deal, making it much easier to add new heretic paths.
