Refactors + firefox + shell helper script

Moved each virtualhost related to a service into that service file.
Set up firefox syncserver.
Moved to using home-manager to fully manage firefox profiles.
Moved waybar into its own folder.
Moved NUR into sources. Stopped using sources for arc's scream package,
so on.
