0.2.0 alpha 1.19.3

This release breaks compatibility with the previous versions

Big update. I've been quite hesitant to release it because I can't do much testing myself and have gotten quite a bit of feature creep...
There will definitely be patches soon as I become aware of more and more issues.
For now, here are some of the more major changes:

• Proper GUI
• Trinkets support
• Developer API
• Custom XP droprate formula

A lot has been rewritten to make things more future proof.
