Merge remote-tracking branch 'upstream/master'

And not return false if not a player(ie:mobs api) or unknown node, continue iterate on others areas(minor bug, generaly if 1 area it's protected).

+Areas mod for Minetest
+======================
+
+Dependencies
+------------

+Minetest 5.0.0+ is recommended, but 0.4.16+ should work as well.

 Configuration
 -------------
 
-If you wish to specify configuration options, such as whether players are
-allowed to protect their own areas with the `protect` command (disabled by
-default), you should check config.lua and set the appropriate settings in your
-server's configuration file (probably `minetest.conf`).
+Open the tab `Settings -> All Settings -> Mods -> areas` to get a list of all
+possible settings.
+
+For server owners: Check `settingtypes.txt` and modify your `minetest.conf`
+according to the wanted setting changes.
+
 
 
 Tutorial
 --------
 
-To protect an area you must first set the corner positions of the area.
-In order to set the corner positions you can run:
+1) Specify the corner positions of the area you would like to protect.
+Use one of the following commands:

   * `/area_pos set` and punch the two corner nodes to set them.
   * `/area_pos set1/set2` and punch only the first or second corner node to
 	set them one at a time.

   * `/protect <AreaName>` -- If you have the `areas` privilege or the server

+
+If you are making a protection mod or a similar mod that adds invisible regions
+to the world, and you would like then to show up in the areas HUD element, you
+can register a callback to show your areas.
+
+HUD handler specification:
+
+ * `handler(pos, list)`
+   * `pos` - The position to check.
+   * `list` - The list of area HUD elements, this should be modified in-place.
+
+The area list item is a table containing a list of tables with the following fields:
+
+ * `id` - An identifier for the area. This should be a unique string in the format `mod:id`.
+ * `name` - The name of the area.
+ * `owner` - The player name of the region owner, if any.
+
+All of the fields are optional but at least one of them must be set.
