3.0.0-beta.7

• Added a new /ct migrate command which can handle most incompatibilities when upgrading
• Reverted previous merger of Renderer and Tessellator, but Tessellator has been renamed to Renderer3d. It does not necessarily have the same API, as it now holds 3D-only methods.
• Fixed a few obscure Mixin issues
• Removed the parameterName option in various Mixin objects, since it will never work outside of a dev environment
• Stop converting Java Collections to JS arrays. This allows Collection objects coming from Java to be modified
• Fix Scoreboard.getLines() returning empty strings
  • Also made scoreboard functions return TextComponent instead of string
• Fix custom KeyBinds not being persistent between game launches and sometimes causing crashes
• Fix Item.getLore() triggering the Fabric tooltip event
• Fix calling .trigger() on a custom trigger at the top level not working
• Fix messageSent not propogating the leading / character if the message was a command
