lcarswm 20.3

Release 20.3 of lcarswm is here :D

There's added support for a status bar and it's running on Kotlin 1.4.*. Is that all? Well, for the lcarswm there are mostly some internal changes bus not much, we cleaned up a little, but the major things happened around the window manager. Python sources got extracted to their own repositories and lcarsde is now there as well, woohoo.

Check out the Changelog for all the changes.
