1.16.5 - 1.4 Snapshot 1 - MCreator 2021.2 and Small features

This version is a beta version for the next major version. In this snapshot, the generator has been fully updated to support the latest snapshot of MCreator 2021.2. Variables got a new scope, Global session! Unsupported fields are now disabled and a bunch of new small parameters from MCreator 2021.2 or old versions have been added. I'm releasing a snapshot because as I explained in the previous update, MCreator 2021.2 breaks a lot of things in the code and I also added a bunch of new features, so I want to be sure to have the fewer bugs possible. I plan to release the full update just after the release of MCreator 2021.2, so depending on when it will be, the full release should be a few hours or maybe the day after.
