Industrial Control Widget Library (AICWL) 3.24.1 (#179)

* Add AICWL to index.

* * Fixed wrong location of crate file.

* * Use gtkada, not libgtkada (not sure if that makes a difference at this point).

* Dependency on gtkada^17

This seems to be the latest version (at least with GNAT CE 2020).

* Update aicwl-3.24.0.toml

Require "at least" gtkada 17, instead of "exactly" 17.

* * Release repository restructured.
* License fixed (it actually has the linking exception, so it's GMGPL, not GPL.)
* Added patch level version number.

* * Improved upon alire.toml:
  * Compilation of all examples and test programs.
  * gpr-externals
  * Description(s)

* * Disabled building of (most) executables due to missing libraries.

* * Deleted crate version 3.24.0.

* Update aicwl-3.24.1.toml

Removed executables.
xpm2gtkada would be one to be build, but right now this requires simple components which is not packaged (yet).

* Update aicwl-3.24.1.toml

+description = "Ada Industrial Control Widgets Library"
+long-description = """
+This crate provides a library for designing high-quality industrial control
+widgets for Ada applications. The software is based on
+[GtkAda](https://docs.adacore.com/live/wave/gtkada/html/gtkada_rm/index.html),
+Ada bindings to [Gtk+](https://www.gtk.org/), and
+[cairo](https://www.cairographics.org/manual/index.html).
+
+The key features of the library are:
+
+* Widgets composed of transparent layers drawn by cairo
+* Fully scalable graphics
+* Support of time controlled refresh policy for real-time and heavy-duty applications
+* Caching graphical operations
+* Stream I/O support for serialization and deserialization
+* Ready-to-use gauge, meter, oscilloscope widgets
+* Editor widget for WYSIWYG design of complex dashboards
+
+For further information, visit the
+[AICWL website](http://www.dmitry-kazakov.de/ada/aicwl.htm).
+
+Maintainer's note:
+
+This Alire crate is packaged in a rather minimalistic way to keep dependencies
+on external libraries at a minimum. The crate's definition covers the core
+functionality of AICWL, though, so it should be sufficient for most needs.
+
+For example, the original distribution has references to
+[Simple Components](http://www.dmitry-kazakov.de/ada/components.htm) which are
+not strictly necessary for the core functionality of the library.

+# Note: Object_Dir works as follows: If it's ".", it will remain so, if it's
+#       "nested", Object_Dir will become roughly obj/{OS}/{arch}/{Development},
+#       e.g. "obj/linux/x86_64/debug", all other cases result in Object_Dir
+#       being unchanged.
+#       Hence we should leave it as is (the default is "."), trusting Alire to
+#       set an appropriate one.
