Misc updates I've thought of doing

[bsquidwrd]

• Implement L443 with cancelling all active searches
• Edit L444 to say 'cancelled' instead of 'purged'
• Make things cross server capable by adding a 'Server' table and logging the server with a Search
• Add a '!whoplays' command to figure out who has played a certain game in the past
• Make web based and dashboard
• Make credentials.py pull from environment variables instead (SQUID_BOT_TOKEN, SQUID_BOT_CLIENT_ID, SQUID_BOT_OWNER_ID)
• Command aliases (like here)
• Ignore everything bots do, including status changes etc
• Show a user who is also queued for a game and ask if they want to continue queuing or start a party with the people searching (max 5?)
• Show number of people searching next to the game name
• Make a model for server specific information for a user. Ex: Display Name can be specific per server: https://discordpy.readthedocs.io/en/latest/api.html#discord.User.display_name
• Modify the README.md to talk about cross server stuff and encourage them to not run an instance of this bot
• Add field to DiscordUser Model for avatar and default avatar urls as well as a function to get the avatar url (ex: if avatar_url is not set, returns default_avatar_url)
• Fix whoplays command. Doesn't show list of games available to check for
• Make restart command do self.bot.logout instead of .close
• on_member_join, update a user and server relationship
