2acefb2660 terrainlib: compute current queue length instead of using '#' operator. 
Important speedup.

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)

6564d40b85 Refactor grid loading and reorganize code 
Move grid management functions out of polygons.lua, in a new file called gridmanager.lua
Explicitly call other files and grid management functions from init.lua
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.

74733549df Various bugfixes and workarounds 
Now working in pure Lua!
Some parts of the code are very hacky (e.g. noise) and the way new and old codes have been glued together is sometimes to be rewritten.
But at least it works.
