Release Notes: 0.755.4

I've decided to upgrade the game to Unreal Engine 5. This will be a good amount of work, so I am releasing what I have before starting that process. 

UE5 is a substantial upgrade over UE4, and should finally allow me to fix the janky lighting and other quirks. UE4 has no true realtime lighting system, so since the game launched I have been faking it with tricks that aren't ideal. Additionally, my style of level design will benefit greatly from UE5's new Nanite system.

Thank you for your continued patience while I deal with mental issues.

• Improved sharks, presets will need adjusted

• Fixed issues with vagrants and tentacles
