Additions

Multi-bot support. Guilds and tournaments with a high match load can now host multiple lobbies at a time with multiple steam bot support. Running npm run steam for the second time will prompt you to add a second bot, or remove an existing one.
MMR Support. The bot is now able to fetch users' MMR from OpenDota. Additionally, displaying MMR can be enforced through an option in config.js, preventing players from joining any events if they don't display their MMR publicly.

What the bot cannot do is restrict an event to a range of MMR, but might in the future.
Added cmpick flag to the add-inhouse command, to decide who gets the first pick.
Added add_inhouse_is_admin_command option to config.js to give admins the ability to prevent regular users from adding inhouses to events.
Added game_generic_name option to the config.js so "Inhouse" can be relabeled to things like "Lobby" or "Match". This is useful for tournaments, where matches are not technically inhouses.
Status command. This is an admin command that sends information about the bot. Currently: its uptime, and the status of all steam bots.
The bot is now able to detect the match ID on ticketed lobbies. In the future it might do useful stuff with the match results.

Changes

Due to multiple lobbies being able to be hosted at a time, commands like resend-invite and force-lobby-start now require you to pass the event ID.
Expired events are now unpinned from the master channel.
