CastAPI 17w26a Snapshot

Here we go again! Time for the second snapshot of CastAPI.

New Features

• Added an experimental permissions system! Read up on it here
• Plugins can now be enabled/disabled
• Added informative embeds to the EmbedBuilder
• The version is part of the CastAPI exports
• The CommandsManager now has a method to duplicate groups when you will be making modifications to it that you do not want to reflect globally
• CastAPI supports DMs!

Important Notes
The permissions system is likely to change in the next few snapshots. The change will be minuscule but break commands that implement the permissions system.
