nvim repo has been converted to flake for easier inclusion but still
stand-alone for non-nix systems
Move tokyonight repo fetch to flake input to keep consistent and reduce
multiple fetch calls
Reduce complexity and in flake.nix and be more efficient in re-using
things
Removed some reduandant files in home/ and tidied up the structure
somewhat
Moved things from desktop, gui, etc... to top level
Changed env to shell, indiv shell expressions import relevant others
