Discord bot commands & OAuth Integration

Users can now sign up using discord using the OAuth. Also the discord bot now has the following commands: /mystats - Pilots can type /mystats in Discord and get an ephemeral (private) embed showing their own stats: total hours, rank, recent PIREPs, standing. /book - show a pilot their upcoming bookings directly in Discord.

VATSIM/IVAO Integration

Users are now able to link their VATSIM and/or IVAO or even sign up using these networks.
