Add shell to job dict
Remove unnecessary call to generator when updating cron units

systemctl daemon-reload already takes care of deleting old unit files
and executing the generators again.
Add path unit to monitor changes to crontab files.

Add systemd-crontab-update.path and .service files to monitor changes
to cron files and start systemd-crontab-update when necessary.
Use try-restart cron.target to only start it when it was active before.

Using try-restart cron.target gets only restarted when it was started before,
this way it won't get started when the administrator has decided to not enable
or start it.
remove update() function from crontab
Update README.md to not reference systemd-crontab-update for crontab command.
