[v0.11.0] Loading Youtube playlists + bug fixes

Features:

• &play now also works if you add a YouTube playlist (only works if you use the list page, not a video with a list embedded in the link.) This is currently limited to 50 songs due to an internal limit in youtube-node.

Fixes & updates:

• Many fatal exceptions have been fixed by @mderveeuw, thanks!
• Some internal restructuring makes the code easier to read and adapt for yourself.

[v0.10.0] Multi-Server Support

Features:

• &np - See how long a song has been playing for.
• &status - See stats about the current process.
• &reboot - exits the process to trigger process managers like pm2 to restart the bot. Needs to be enabled in config.json to work.
• The whole queue has been reformatted to allow the bot to play on multiple servers at once.

Fixes & updates:

• Robotto is now much tidier, cleaning up both issued commands as well as his own messages.
• Fixed the playlist system to work on UNIX based systems.
• Fixed previously fatal errors
• You can now set Robotto to update its profile picture by adding "avatarURL": "{url-to-image)" to the config file.

[v0.9.0] Playlists & more

Features:

• &playlist - Robotto will now load playlists found in ./playlists. playlists have to be .txt files with alphanumerical names. Contains YouTube links seperated by line breaks (i.e. one link per line)
• &voteskip - You can now voteskip a song. Amount of votes required is the amount of listeners devided by two and rounded up.
• Added MasterDJ in Config - You can now determine MasterDJ users in the config file. Use a person's user ID. You can add multiple people in the array.

Fixes & updates:

• &skip now only works if the user is found in the MasterDJ array found in the config file.

[v0.8.1] Ready for use
