Bring manta back to main servers

[Kotlol]

It was an unfinished map with problems apperently.

I liked it too since it was unique and had fun areas. I also loved the sea-turtle cause it was a huge mining/side engineering bay. But that got removed since 90% of it was kinda pointless.

I don't know the details but I know programmers did not like it. Though design wise it was a fun place to navigate.
