Update V0.0.4 Beta

This semester we've been focusing on updating the visuals, because we've decided that 2d is just more work than it's worth in this instance.  (Artists, why did you not stop me earlier?)

So, all but the turrets and bosses have been replaced with 3d assets, and the player's been replaced with a 3d asset.  (All from a couple asset packs.)  All but the walk, idle, and jump/fall animations on the player are from our new artist who's been figuring out how to rig and animate for Unreal Engine, but all the NPC animations are from the asset packs they came from.

We've also updated to Unreal Engine 5, and started using the new data-layer system to load the levels instead of a level system.  This optimizes a few things to be much nicer, (We don't have to load everything just to access all the containers.) and should make it easier to work with in the future.

However, because of time constraints in this release we had to disable the archer class.  (Hopefully we can re-add them in a week or so, as there's only one new animation needed.)  Because of this, the old version is still up to play with the ranged class if you desire.
