Fleet-up extension

[HunHawk]

I found 2 annoying errors:

1. When the bot posts new/upcoming fleet ops, the doctrine's names are nem formatted:
   Planned Doctrines: [{'Name': 'Doctrine name', 'Id': 12345}]
2. When someone ask fleet ops with !fleets command, the bot answer to him in that channel where az user asked even in general channel too. I already set the correct channel ID in config.py. I see 2 solutions for this: restrict the usage of this command only in allowed channel(s) or doesn't matter where is the user use the command, the bot only posts the reply in the allowed channel.
