- Fixed the other arena files show up as separate playable arenas
- Finally changed Cut off name to not include "_"

Added a test background sounds to every arena, most likely they will be changed again.

- Small change to Coliseum and two other arenas which seemed to have quite long load time, not sure if that fixes the crash issue but gonna see

- Remade "Collapsed" arena, more trash looking now hehe
- Little adjustments of decreasing competetive spawns slightly

Modified most arena spawns, not significantly in most cases but gonna see how it will turn out.

"Coliseum" arena has been rerendered with a bit more dens to spawn creatures from.

"Shrivelled" arena also rerendered with less eye sore of random concrete blocks around the arena.

Test update
"Funny" spawns for one arena has been edited to be worse
