Bug fix Ocean Biome

Now bug fixing some bugs that got brought up by fellow players Snow_Princess & LordFartquad found 3 seperate bugs.

-1: player is able to mine/remove seeweed which leaves a empty air space in ocean. Not suppose to happen for now ill make it so player isnt able to do anything with seeweed just for decoration however in future there will be a few things to do with seaweed.

-2: Player is able to swim down generating the spawning in of many jellyfish then when player dies from either oxygen loss or jellyfish stings the player is toss back to spawn but ALL the jellyfish that got rendered in still in world which lags game since player is now THOUSANDS of blocks away from Ocean Biome and jellyfish dont despawn when player not near..

-3: Player Quest to open up Teleporting to Ocean Biome isnt saveable at the moment which shouldnt happen.

** Ill fix all this issues before moving on with the Forest Biome update**

That way the game isnt full of bugs. I tackle bugs soon as i find them so the only bugs i have known is in the newer codes. 

Thank you guys for playing and reporting bugs!!!

I want it 0 known bugs for Multiplayer launch
