* this solves: closes https://codeberg.org/minenux/lavastuff/issues/1
* close https://codeberg.org/minenux/lavastuff/issues/1

* real fix for compatibility later trasnlations

* real fix for #13
* use native translator or intlib property as must be, but mock if both fails

* fix modname and use intlib depennds only in older engines

* autodetect mod name from minetest api
* added only intllib in depends.txt for older 0.4.X, mod.conf its for 5+
  so due 5+ has built in internationalization its not necesary in that file

* added the depends only when necesary for intllib

* Update init.lua usage or MODNAME and MODPATH
