Added token validations (channel token does not exist yet so ignore the message it sends).
IsFollowingChannel has been renamed to IsFollower.
Shorter code for the follower checks.
Spreadsheet subs checking function has been moved to the Api class.
Better code for transactions updating (from Stream Donations but helps towards the transaction to Stream Tip).
Added a class for easy modifications that don't require editing of the actual bot.
Added a command adding demo class which uses the modifications class.
Removed the list of handlers in the Command class inside Commands.
Base code for channel's auth token.
Fixed accidentally enabling the other giveaway options, they're not done yet and so shouldn't be used.
