services: Fix commit_notes service autostart

Used wrong 'after' designation which would wait forever since it needed
to start after the runlevel which it was designated to run at.

Committed default.target.wants symlink to service file to automatically
enable its autostart on new machines.

This wil only really work for my directory set-up, so perhaps either the
service module should be disabled by default for the installation, be
asked during installation, or simply be manually enabled to autostart
during initial set-up (maybe mention in readme for the module).
