shoutouts to Blueberry_pie for the original work

TODO

• [x] seperate csm from the editor into its own entity (allows menu but also keeps editor as i like being able to spawn it in) (this is sorta done so i checked the box)
• [x] performance mode for lower end computers (2 rings only but same ring size?? idk)
• [ ] partition the frustum into subfrusta (like normal csm implementations, better on performance)
• [x] research better methods for disabling sun (if possible, I doubt)
• [ ] hammer integration so map makers can specify settings for the csm
• [x] MAKE A GODDAMN ICON FOR THE ENTITY IN THE SPAWNMENU
• [ ] Really shitty and cheap global illumination (probably very hard to do so this is unlikely)
• [x] Shadow spread in the closest ring (maybe second ring too, yknow for insane people)
• [ ] Weapon self shadowing
• [x] Firstperson player shadow
• [x] disable warnings option
• [ ] Sqaure texture for projtext for slightly better use of space???
• [ ] rewrite cause all this code is messy and kinda sucks

TRY TODO MORE

• [ ] performance, it's fine right now but no reason I cant try to improve (even tho i dont think i can at all)
• [ ] fix decals on props somehow
