Add alternative starter for scala

[CGjupoulton]

I don't know much about scala. Why do we need an alternative starter?

I personally dont like the provided one. This one is a bit cleaner and provides more data out of the box (grow action cost, seed cost and seed destination richness via seedAction.destinationCell.richness etc.).

There is no drawback of hawing two starters in the repository :)
