treewide: modules -> profiles, separate dirs, list in README (#29)

Enforce proper naming: all paths are lowercase and hyphen-separated,
if there's a line of models (aspire, macbook-pro, thinkpad) it becomes
a subdirectory. Documentation for profiles is moved to README files in
respective directories.

Add an Org mode table that lists all available profiles and their paths.

Instead of fetching repo locally, use a Nix channel. Making hardware
profiles read-only should improve quality and amount of participation
long-term.

-A collection of NixOS modules covering hardware quirks.

-## Usage
-The simplest way to use this repo for now is to clone locally and include by path:
-``` nix
-{ config, pkgs, ... }:
-
-{
-  imports =
-    [ /home/user/nixos-hardware/acme/thunkpad-2000.nix ];
-}
-```
-
-Modules should favor usability and stability, so performance hacks
-should be activated by an additional a NixOS option or conservative
-and performance configs can be declared in seperate modules.
-
-Because modules can only be tested with the appropriate hardware,
-quality assurance is up to **you**.
