The dedicated editor module for NixOS has been removed seeing as it is
barely used. The only exception is Neovim which is moved into
`modules.dev.neovim`.
- Add `modules.desktop.cleanup` for the usual cleanup activties in
NixOS.
- Update to proper descriptions for module options added with
`lib.mkEnableOption`.
- Additional packages for various modules.
- Deleted `modules/home-manager/alacritty`. It is pretty useless though.

I think this is better for separating modules explicitly. This is also
considered as there are similar objects between modules (e.g., NixOS
and home-manager modules and users).
Revert users module to old position
