Add options to desktop.nix from home/default.nix that are
desktop-relevant.
Add mimeapp config back from nixos system config
Move fd, ripgrep to enabled programs, remmina to enable service
Emacs config now imports shell config to ensure requirements are met
instead of duplicating some
Move Zsh config into it's own file zsh.nix
Move sway to desktop/sway and move other packages under programs/sway
up a level to programs/desktop, add niri config to desktop/niri and
refactor common desktop imports into desktop/default.nix that also
imports (for now at least) sway and niri modules
Move wallpapers into programs/desktop since that's where they're
needed anyway
Add helper script to call swaybg with arguments
