Refactors for usability

Using ./home.nix and ./nixos.nix as entrypoints for hosts.
Using hardware profiles.
Using new entrypoints (profiles/base/profiles.nix + profiles/base/home.nix).
New modules (for DNS handling, for themeing, ...).
Split up deploy-tf.nix into several modules.
Renamed common profile to base profile.
