BUILD

Github Actions windows-latest provides msys2 by default so no need to fetch it. Just make sure to add it to the path actions/runner-images#104 (comment). Also make sure install/configure it to use the posix thread model

But https://github.com/msys2/setup-msys2 is faster so might be worth looking into later. Read https://github.com/actions/virtual-environments/blob/master/images/win/Windows2019-Readme.md for the full list.

Proposal for Changes to Visual Scripting System

AIMS OF THE PROPOSAL

• Moving towards modularity
• Simplification and accessility for customization of the scripting system
• Reloadable and Debuggable chunks
• Cleaner and robust utilities while scripting
