I'm trying to make it so that the external mapgenerator can be really
simple, ie so it doesn't have to worry about all these details, but it
can if it wants to. If an external generator wants to add rivers, it
just needs to say "have_rivers_overlay", and provide the appropriate
data. If it doesn't want to worry about rivers, the default algorithm
will be run.

Huh. I'll try again.
