Switch completely to SDL2 version

The now legacy version of LimoX with GTK4 and libstrophe is now not part
of the main branch anymore. There might be a legacy branch keeping this
version at the time of reading.

This cut of implemented functionality is motivated by these reasons:
- Implementing XMPP is fun, educative and gives full control.
- Low level graphics with SDL2 is portable, fast, educative an mature.
- I do not have to use GLib and a crazy event loop anymore (run and hide)
