The user dumbhighrank mentioned on Discord that it was not possible to
call enable-autostart with the --ffm flag, as one might expect to be
able to do, given that it is accepted by the start command. This commit
introduces the --ffm flag for the enable-autostart command.
This commit adds a new komorebic quickstart command to handle the
downloading of example configuration files, which is currently done
manually by the user if they are following the quickstart guide on the
README.
