v2.0.0

Squishy 2.0 has released!
There's still some code formatting and other bits for me to do, like adding more stuff to the fun module, but I'm satisfied with what I have.

There's currently;

• Autoroles
• React roles
• Catchphrases (Say a random line from an admin-defined list when pinged)
• Custom extensions/scripts for shop items
• An economy + shop
• Fun (Just coinflip, more games soon)
• Levelling
• Message builder (build embeds from json, then send them)
• Stars (Reward member engagement with gold stars)
• Welcome (Welcome new/say farewell to leaving/roast banned members)
