1st 2021.3 snapshot - Full Minecraft 1.17 support

It is finally here - MCreator that fully supports Minecraft 1.17. And not just that, it also greatly improves the generated code. The code of 1.17 mods is much cleaner, faster, and human-like!

The snapshot may not be the biggest, but it has a lot of great changes under the hood, in terms of performance, code quality, plugin options, and much more.

Snapshot changelog

Major new features in this snapshot are highlighted with bold text.

• Updated bundled Java to version OpenJDK 16
• Added base support for Minecraft Forge 1.17.1
• [FG 1.17.1] Added support for mod elements: advancement, fuel, command, overlay, food, painting, procedure, tag, function, dimension, loot table, recipe, music disc, key binding, potion effect, potion item, GUI, armor, particle, structure, block, plant, biome, custom element, fluid, item, enchantment, game rule, tool, ranged item, living entity, and creative tab

Release notes

• Java entity models before 1.17 are not compatible with 1.17 and vice versa. Two separate instances with the same name need to be imported, one for an older generator and one in 1.17 generators and MCreator will pick the right version depending on the current generator
• [Plugins] Generators can now use global templates for each mod element type
• [Plugins] Generators can now use common definition files for different base types
• [Plugins] Generators no longer need to define partial support for mod elements as MCreator automatically detects coverage support using excludes/includes parameters.
• [Plugins] Variables and procedure categories can now use hex color codes

Credits

I would like to thank all the great contributors that helped with updating MCreator to support Minecraft 1.17. There are a few hundred procedures to cover, tens of mod elements, some of which are very complex so without the help of all those amazing people, this update wouldn't be there that fast for sure.

Make sure to install and test this snapshot, so we can get it to a stable release as soon as possible :) Leave a comment, feedback and stay awesome!
