Version 0.1.3 - Remote updating now better & more commands

This release, compared to 0.0.4, adds DM handling and special commands specifically for DMs, adds the capability for the bot to be updated remotely with an update command through DMs, restricts permission setting to the bot owner and guild owner by default (others can be added), adds support for adding a user to a permissions list by said user's username and discriminator instead of being forced to use their discord id, modify the way files.json formats data to list file paths by folders instead of listing full paths for every file, and remove the use of the loop keyword argument in any instance of asyncio.gather because it's apparently going to be depreciated.
