Migrate to on_socket_event_type event

Discord.py 2.0 (Namely this commit Rapptz/discord.py@e2250d4) removed the socket_response event, and replaced it with the socket_event_type event, which just sends the type of event triggered on the websocket.

Since this event was removed, no socket stats were being incremented, as the event never triggered.

I have looked through the rest of the bot, and we do not use the socket_response event type anywhere else.
