156: Improve Home Manager support: profiles/suites, modules, extern, flake outputs r=Pacman99 a=Pacman99

A really simple method of implementing #119. 

This relies on a feature that I added in home-manager master for module options of extraSpecialArgs and sharedModules, nix-community/home-manager#1793. I could try and get that backported to 20.09. But I thought I'd get some feedback on these changes first.

## Home Manager
Home Manager support follows the same principles as regular nixos configurations.
All modules defined in [user modules](./modules/module-list.nix) will be imported to
Home Manager. All profiles are availabe in [suites](../suites/default.nix) as userProfiles.
The `userSuites` output will be available in your Home Manager Configuration as
the special argument, `suites`.
## External Usage
You can easily use the defined home-manager configurations outside of NixOS
using the `hmActivations` meta-package defined in the flakes `legacyPackages`
output. The [flk](../doc/flk) helper script makes this even easier.
using the `homeConfigurations` flake output. The [flk](../doc/flk) helper

This is great for keeping your environment consistent across Unix systems,
including OSX.
