Use seed for world generation

[Hopson97]

Suggestion Title Using a seed to create different world gen

Describe your suggestion Right now the world generation is the same every single time However to be more interesting, it would be better if a seed were somehow used to create different results

Implementations ideas [optional]

Not sure

[rehwinkel]

Should the seed be stored in a world-file of some sort?

[Hopson97]

Probably will be yes.

For now there is no world file though, so not worrying about this for now.

The way I am seeding atm is by passing a seed into the third parameter of "3D Simplex Noise", which would give a unique slice of that noise, but its not the most effective (as you can imagine, a seed like 3423 would be basically the same as 3424)
