Added alacritty into home manager management. Config has been
moved and the Nord theme has been set inside of the config now
instead of as an import in the name of making it more portable
(and the cost of making it more expensive to change later).
Set users.mutableUsers to false to make all user creation declarative.
All users now must be defined in configuration.nix and make sure they
have hashed passwords set.
This is the initial commit of our Nix configurations. base-config.nix
will be a base configuration that any specialized configurations
(desktop, laptop, etc) may be based off of in the future. wes-home.nix
is our configuration for Home Manager.
