This supports Discord as an auth provider. It depends on the next
release of the Arcade Engine to work, so ~we'll hold off on merging for
now.~ we'll do it live!
* Renamed `arcade_arithmetic` to `arcade_math`
* Deleted `arcade_github` toolkit for the next release. This will be
reintroduced later.
* Added 5 tools to `arcade_x` toolkit
- post_tweet
- delete_tweet_by_id
- search_recent_tweets_by_username
- search_recent_tweets_by_keywords
- lookup_single_user_by_username
As the title states.
Also added in a prompt/execute capabiltiy into the CLI for the ``arcade
run`` command
