[Suggestion] World limit and client_protocol in config

[CWz]

Currently to change the worldlimit once has to edit constants.h and recompile minetest.

Would be great if it were possible to do this via minetest.conf or set it in map_meta.txt

Also it would be nice if a minimum protocol could be defied in minetest.conf rather then the current bool limitation.

I created a basic script to limit the world using unbreakable nodes, and can be configured to all six dimensions. However, it is very basic in how it creates the world limit. It also generates outside of the field to make the world look nicer.

It will probably be part of the next version of mt.

The network protocol version is already possible using the setting ending in _min and _max.
