* bushes ground content
minetest default game treats all bush parts as ground
content, so we do that here too. The baskets however are
player made and placed, so they aren't ground content
* cavestuff ground content
Pebbles are given to mapgen as decorations, so they have
been left as ground content.
The stalactites are not ground content
* user 'placed' nodes -> not ground content
* ground content revision
idea taken from homedecor_modpack and its homedecor_i18n
all translated mods have a new dependency : plantlife_i18n
translations are stored in po/pot file : one file for all mods
added french translation (almost complete)
transfered de/es/tr/pt translations to corresponding .po file
(only for some mods, unfortunately translations are incomplete)
