Map Discord events to API events

[Kiskae]

All of the events that are being sent by Discord:

• CHANNEL_CREATE => ChannelCreateEvent.* for Public and Private channels
• CHANNEL_UPDATE => ChannelUpdateEvent
• CHANNEL_DELETE => ChannelDeleteEvent.* for Public and Private channels
• MESSAGE_CREATE => MessageCreateEvent
• MESSAGE_UPDATE => MessageEditEvent and MessageEmbedEvent since Discord sends an 'update' when it finishes parsing for embeds
• MESSAGE_DELETE => MessageDeleteEvent
• MESSAGE_ACK Not sure if applicable to the client, mostly for gui clients.
• GUILD_CREATE => GuildCreateEvent
• GUILD_UPDATE => GuildUpdateEvent
• GUILD_DELETE => GuildDeleteEvent
• GUILD_MEMBER_ADD => MemberJoinedEvent
• GUILD_MEMBER_UPDATE => MemberUpdateEvent
• GUILD_MEMBER_REMOVE => MemberLeftEvent
• GUILD_BAN_ADD => BanCreateEvent
• GUILD_BAN_REMOVE => BanRemoveEvent
• GUILD_ROLE_CREATE => RoleCreateEvent
• GUILD_ROLE_UPDATE => RoleUpdateEvent
• GUILD_ROLE_DELETE => RoleDeleteEvent
• USER_UPDATE Sent whenever the user changes their account properties
• READY Initial event to set up the model, potentially could be mapped to an event that signals that the model is ready.
• TYPING_START Indicates someone started typing, not sure about a use-case
• PRESENCE_UPDATE Sent whenever the idle state or game played changes, very VERY spammy.
• GUILD_EMOJIS_UPDATE Sent whenever discord updates the automatically updated emoji's
• GUILD_INTEGRATIONS_UPDATE Sent when discord completes the integrations update
• VOICE_STATE_UPDATE Sent whenever the voice state (deaf/mute) changes
• RESUMED Not yet encountered and there is very little documentation
• GUILD_MEMBERS_CHUNK Not yet encountered and there is very little documentation
• USER_GUILD_SETTINGS_UPDATE Not yet encountered and there is very little documentation
• VOICE_SERVER_UPDATE Not yet encountered and there is very little documentation
