0bc100030c terrainlib_lua: Hardcode flow_local for performance 
as it is unlikely that it will be changed one day.
This results in a drastic performance improvement (x4 speed for step 1)

to make workflow more apparent
Move mapgen loop out of init.lua, into mapgen.lua

7e155b7076 Express map size in Minetest nodes, not in river grid nodes 
This introduces new parameters 'map_x_size' and 'map_z_size' that default to 15K
Deprecates 'grid_x_size' and 'grid_z_size'; if they are present, corresponding
values of 'map_x_size' and 'map_z_size' are automatically written in config files.
Also rework compatibility system to better compare versions,
and bump version to 1.0.2-dev1.
