- This removes `intllib` depends. I used
https://github.com/FaceDeer/update_translations to convert from existing
translation files (plus manual edit).
- Removed translation string from `minetest.log` calls since translated
string are not printed in console.
- Changed formspec in `barter.lua` to allow longer strings to be displayed
(player names, and longer translated strings).
- French translation improvement.
based on the notion that since one US nickel weighs exactly 5 grams, and
1 Minegeld cent equals 1 US cent, thus 1000 5-cent Mg coins would be
5 kg. Still a huge amount to carry :-) but not unreasonable.
