Bump version to 4.0.2

GTK 4 centers marks of the Scale widget even when the scale has a vertical
orientation. Unfortunately, the Scale widget does not provide a way to set the
alignment or to access the internal Label widget in any way. To left-align the
labels this commit add a method that traverses the all children of the songs
scale recursively and adjusts the alignment if it is a Label widget.

+# CoverGrid
+
+CoverGrid (mcg) is a client for the [Music Player
+Daemon](http://www.musicpd.org) (MPD), focusing on albums instead of single
+tracks. It is not intended to be a replacement for your favorite MPD client but
+an addition to get a better album-experience.

+
+License: [GPL](http://www.gnu.org/licenses/gpl.html) v3
+
+Dependencies:
+
+* [Python](http://www.python.org) 3
+* [python-dateutil](https://pypi.org/project/python-dateutil/)
+* [GTK](http://www.gtk.org) 4 (>= 4.18) ([python-gobject](https://live.gnome.org/PyGObject))
+* [libadwaita](https://gnome.pages.gitlab.gnome.org/libadwaita/) (>= 1.2)
+* [Avahi](http://www.avahi.org) (optional)
+* [python-keyring](http://pypi.python.org/pypi/keyring) (optional)
+* [meson](https://mesonbuild.com/) and [ninja](https://ninja-build.org/) (building)
+
+Additionally a [MPD](http://www.musicpd.org) server (version >= 0.21.0) is
+required at runtime.
+
+
+## Building
+
+Build the application with _meson_ and _ninja_:
+
+    $ meson build
+    $ ninja -C build
+
+## Running/Testing
+
+For testing the application and running it without (system-wide) installation,
+donwload/clone the code, build it with the `--prefix` option and install it
+with `ninja`:
+
+    $ meson setup --prefix $(pwd)/install build
+    $ ninja -C build
+    $ ninja -C build install
+
+After that you can run it with _meson’s_ `devenv` command:
+
+    $ meson devenv -C build src/mcg
+
+## Installing
+
+Install the application system-wide with _meson_ (after building):
+
+    $ ninja -C build install
+
+Note: _On Linux using the distribution’s package manager is the preferred way
+of installing applications system-wide._

-h2. Building
-
-Build the application with _setuptools_:
-
-bc. $ python3 setup.py build
-
-
-h2. Running/Testing
-
-For testing the application and running it without (system-wide) installation, donwload/clone the code, build it as described above and then use _setuptools_ to install it for the current user:
-
-bc. $ python3 setup.py develop --user
-
-After that you can run it with
-
-bc. $ ~/.local/bin/mcg
-
-or if _~/.local/bin/_ is on your PATH
-
-bc. $ mcg
-
-
-h2. Installing
-
-Install the application system-wide with _setuptools_:
-
-bc. # python3 setup.py install
-
-Note: _On Linux using the distribution’s package manager is the preferred way of installing applications system-wide._
-
-
-h2. Packaging
-
-Create a distribution package with _setuptools_:
-
-bc. $ python3 setup.py sdist
-
-
-h2. Cover/image configuration
-
-Since MPD itself does not provide the cover/image/album art binaries, yet, _mcg_ has to look for them itself. In order to find the images a base folder has to be configured on the Connection tab as “Image Directory”. This value can either be a local (absolute) folder (e. g. /home/user/music/) or an http URL (e. g. http://localhost/music/). _mcg_ then adds the (relative) folder of the audio file to this paths and tries different names for the actual file:
-
-# the album name
-# “cover”
-# “folder”
-
-The following file extensions are used:
-
-# png
-# jpg
-
-The first combination that results in an existing file is used as cover image. If no matching file exists, _mcg_ will try to traverse the directory for any image file as fallback—this is done for local paths only though, not for http URLs.
