1.3.9 update

Some more changes! 1.3.8 was skipped, but has mostly been tidying up and polishing some features. Mostly UI and UX changes, but critically across 1.3.8 and 1.3.9 the animation system has been updated to use layered animation, specifically when attacking and walking at the same time. Previously, the player would slide around while attacking, but by splitting the player bones into a top and bottom animation state i can play the walking and attacking animations independently. It's a pretty minor change but i think it pays off a lot. 

Additionally, i've noticed that hit registration on smaller enemies was pretty bad because the hitbox was attached to the weapon, and by extension tied to the animation itself, resulting in enemies simply not being hit at all. To change this, a "soft aim" system is used while locked on to rotate the upper body towards the enemy to help land a hit. 

In the last version, "Dens" were not being properly "hydrated" from the imported 3d scene, resulting in a den including the duplicate number (for example, a den that spawns 5 wolves is called DEN_WOLF_5, but can be called DEN_WOLF_5.001 if there's multiple in the scene), so it tried to spawn 5000 entities rather than 5. That's been fixed as well! Gates that can be triggered by mechanisms are in the game too, allowing for more engaging level design. 

Finally, the input system is no longer tied to frame rate like it was before, which resulted in laggy inputs if the framerate was too low, this should be fixed, and the 500ms delay between interacting with objects has been reduced, and even better interacting with objects is based on the direction you're looking in, rather than prioritizing the first interactable object you were standing near. Also a new "class" has been added, the Vagabond. Currently the class variation is pretty shallow, but later more depth will be added.
