Pull program expressions inside hyprland directory (e.g. rofi, waybar,
etc...) up one level.
Convert everything into package-name/default.nix format for
consistency
Move common home imports from flake.nix into hyprland/default.nix,
flake.nix now only defaults into importing hyprland, to be consistent
with how system imports work
Remove some old files: calendar and contact setup, sweet theme pkgs
Move xdg.configFile expressions from home/default.nix into a
config/default.nix, keeping the files to be linked in the config dir
as well (still need to do ipython though)
