shared/nixosModules/style: use sharedModules

As an initial step towards refactoring the theming module, the options
have been split up from the configuration itself. This will allow to
find available options quicker, and separate concerns nicely. It was
also renamed to style, to avoid confusion with its own options (eg.
gtk.theme).

 My configuration is structured based on the following principles:
 
 1. Hosts should be the main entry points and outputs.
 2. Abstractions should be avoided as much as possible.
+3. Setting up theming should be as simple as changing one or two options.
 
-The bulk of the configuration can be found either in [home](home/) or [system](system/), which declares most of my programs, with some extra Nix code in [lib](lib/) and custom [modules](modules/), mostly for convenience and to provide a way to globally set styles and themes for now.
+The main configuration can be found in [config](config/), which declares most of my programs, with re-usable modules and derivations in [shared](shared/), to provide a way to globally set themes, usernames and more.
 
 My hosts can then pick and choose the programs and configurations that they need from the other directories. If the need arises for a more modular setup for a specific piece of software (ie. having different flavors of Firefox per host), I will write a custom module for it. This helps to avoid unnecessarily abstracting my configuration, as I don't find it necessary for the most part, and I would also like it to remain as simple as possible.
