1.0.2

Changed

• Project now properly builds on Stable Rust.
• Switch away from failure to [anywhow] and thiserror for error handling.
• Commands are now run on separate tasks, leading to better performance and
  unlocking the ability to write them in a different language in the future.
• Git version now runs properly. It used to report a User-Agent which caused
  header parsing to crash since it included a newline (e2745e).
• Bumped the version of a lot of dependencies.
• Fixed a bug that causes the bot to crash when it's being restarted and
  improperly using backoff (c0178f).

Added

• More commands are now documented (with examples).
• Added player/playback-mode with support for an alternative, queue-native
  playback mode (#66).
