debug output about how much erosion did occur during water proc.
simulating ten rivers ten times in a row is pretty slow right now...
what takes them so long? even the iteration limit (5000) is hit!

committed screenshot prepared for like half an hour.
did some modifications to make water simulation faster.
Simulation of only 6 rivers is a little bit faster and looks almost as nice.
Merged remote and local branch
How can we get rivers to still hold water after simulation terminates?
little typo
Merge branch 'landscaping'
world initialization
