-  This handles the text input and wide font on/off switch, logging any actions the user takes.  Bails-out silently if the user is not allowed to edit the sign.  See the standard Minetest lua_api.txt for details.

   If the sign's writable, this deletes any sign-related entities in the sign's node space, spawns a new one, and renders whatever text is in the sign's meta.

 This will read through the list of currently-loaded blocks known to contain one or more signs, delete all entities found in each sign's node space, and respawn and re-render each from scratch.
 
 The list of loaded, sign-bearing blocks is created/populated by an LBM (and trimmed by this command if any listed blocks are found to have been unloaded).
