* use tinydm instead of lightdm
* set default term to foot, as alacritty needs a recent opengl version
(issue 984)
* override sway config to actually use foot (there is no
sway-sensible-terminal and upstream isn't interested in adding it)
* set the pmOS wallpaper in the overridden sway config
* add a subpackage that allows changing $mod to Alt, so it's easier to
test this in QEMU while running i3/sway on the host with $mod set to
Mod4
* re-enable previously disabled architectures
* set myself as maintainer
