MCprep 3.5 RC-3

[StandingPadAnimations]

MCprep 3.5 RC-3 introduces @zNightlord's fixes for the JSON model importer (#469)

This means the following are (hopefully) fixed:

• Misplaced block textures (Mcprep spawning blocks with misplaced textures #437, Item Frame (block) #468)
• Models from mods raising errors (Importing mods models #457)
• Scaling being slightly incorrect (Why are individually spawned blocks 1.008 meters? And is there a way to change this? #451, thanks to @FigureOfStickman for providing a fix in Code to manually offset bmesh's scaling problem. It's messy in principle but it works perfectly. #452)

You can download the release candidate here, or build it from the mcprep-rc branch.
