[GunChleoc <fios@xxxxxxxxxxxxxxxxxxx>]

GunChleoc has proposed merging lp:~widelands-dev/widelands/list-directories-in-cpp into lp:widelands.

Commit message:
Improve performance and memory usage when loading tribes and world
- Save memory and loading time by not listing files via Lua
- Common sequential file loading function for image and sound files
- Replace regular expressions with NumberGlob for speedup
- Only load mipmap scales that are being used

Requested reviews:

  Bug #1638356 in widelands: "Implement support for Spritemaps"
  https://bugs.launchpad.net/widelands/+bug/1638356

For more details, see:

Performance :)

I have only converted the directional animations to the new system - the remaining animations will take care of themselves once we move to Spritemaps. Converting them now would cause a lot of unnecessary extra work.

These images can optionally have corresponding player color mask images called ``idle_00_pc.png`` through ``idle_99_pc.png``.

+**basename**
+   *Mandatory*. The filename prefix for the image files. Our example will pick up any image from ``idle_00.png`` through ``idle_99.png`` in the specified directory path -- the current path in our example. These images can optionally have corresponding player color mask images called ``idle_00_pc.png`` through ``idle_99_pc.png``. Make sure to include leading 0's in the file names and to have consistent length -- we support 1, 2 and 3 digit numbers in an animation.

See :ref:`animations_directional` below.
 
 **hotspot**
    *Mandatory*. Hotspots define a place on a graphic image through its *x* and *y* coordinates that can be used as a handle or reference point to provide control over positioning the image on the map. For example, hotspots help carriers stay on the road, and control the positioning of the wares they carry. Increase ``x`` to shift the animation to the left and ``y`` to shift it upwards.

-We support mipmaps for animations. They allow us to provide the same image in different
-resolutions for optimum rendering quality. Let's look at an example with a mipmap ``idle`` animation and a normal ``build`` animation:
-
-.. code-block:: lua

-            },
-            {
-               scale = 1,
-               files = path.list_files(dirname .. "idle_1_??.png"),

-            {
-               scale = 2,
-               files = path.list_files(dirname .. "idle_2_??.png"),
-            },
-            {

-               files = path.list_files(dirname .. "idle_4_??.png"),
-            }
-         },
-         hotspot = { 5, 7 },
-         fps = 4,
-         sound_effect = {
-            directory = "sound/foo",
-            name = "bar",
-         },

-      build = {
-         files = path.list_files(dirname .. "build_??.png"),
-         hotspot = { 5, 7 },
-      }
-   },

-The scale of ``1`` is mandatory, and other supported scales are ``0.5``, ``2``
-and ``4``.
-The base table should no longer contain the ``files`` entry
-when you're using a mipmap.
-Each mimap entry must define the ``files`` and the ``scale``.
