Add aliases for old commands in tutorial video

It would really be ideal to update the tutorial (in which case i don't think this is needed) but if it's not ready in time for the new season (or if it doesn't get updated, though I really think it should be, especially as the gamemode was re-launched after being shut down for over a year) then this is something to consider. Some commands have changed since the old tutorial. /civ info is now /civinfo /civ chat is now /civchat /blueprints is now /cannons It would be good if aliases were added so the commands in the old video work on the current server
