chore: misc (#100) (this makes 2.0.0)

Co-authored-by: grialion <48643945+grialion@users.noreply.github.com>

- Fix license ambiguity (#88)
  - just the only/or-later ambiguity point, not adding SPDX identifyiers unless more people request it
- Better document kmscon (#91)
- Make 2.0.0 already to close #86
- Add a changelog
- Add packagers info (acutally just add them to install guide)
- Add AUR service packages (I'll take care of systemd and dinit, let others package the rest and leave systemd open for someone who actually uses it in docs)
- Make sure all makefile installs to `/usr/local` by default
- Simplify Makefile complexity by several orders

+If you want to add fancy color and font support to your TTYs you can try wrapping lidm in [`kmscon`](https://wiki.archlinux.org/title/KMSCON). (edit appropriate service files). e.g:
 
 ```sh
 kmscon -l --vt /dev/tty7 --font-name "Cascadia Code" -- /usr/bin/lidm
 ```
 
+Kmscon is NOT officially supported so you are on your own when trying this, [according to the arch wiki](https://wiki.archlinux.org/title/KMSCON#Window_managers_cannot_be_started_from_KMS_console) it's not possible to start window managers if you do this.
+
+But [according to farouk](https://github.com/javalsai/lidm/issues/91#issuecomment-3708503568) you can make it work if you tell kmscon to work in `no-drm` mode. There's still input grabbing issues which cause <kbd><kbd>Ctrl</kbd> + <kbd>C</kbd></kbd> to kill lidm, they are likely fixable though.
