Fix winston logging to be primarily single-line

[Throne3d]

Fixes ugly lines like:

2020-08-09T01:55:45.984Z debug: Connecting to IRC and Discord {
  message: undefined,
  level: undefined,
  timestamp: '2020-08-09T01:55:45.984Z',
  splat: undefined,
  [Symbol(level)]: 'debug'
}
2020-08-09T01:55:46.117Z debug: Received debug event from Discord {
  level: undefined,
  message: undefined,
  timestamp: '2020-08-09T01:55:46.117Z',
  splat: undefined,
  [Symbol(level)]: 'debug',
  [Symbol(splat)]: [ 'Using gateway wss://gateway.discord.gg/?v=6&encoding=json' ]
}

To be more like:

2020-08-09T01:54:34.452Z debug: Connecting to IRC and Discord
2020-08-09T01:54:34.567Z debug: Received debug event from Discord Using gateway wss://gateway.discord.gg/?v=6&encoding=json
