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

This will allow to avoid nested 'dofile's

Also cleaned and commented the code

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.

9386ef51f1 Changed the way river width is determined in settings
- min_catchment now in square nodes instead of cells
- River widening power as input instead of calculating it from max_catchment

7e39189368 Load data on request instead of loading everything at first.
Data is cached in memory in case it is reused.
Offset values have a callback that converts them to the range ±0.5

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.

Not tested ; will likely need much testing and bugfix.

83728cc932 Fixed lakes elevation
There were sometimes missing water patches near a lake's edge, when the neighbour catchment area was lower.
This commit allows to divide a cell into several mini-catchment basins, to fill only a part of it with water.

a9ab0e53d3 Change folder structure: data files are now in a directory.
Also added a demo 400x400 map, that is overriden on pre-processing.
