[Draft] Update to 1.20

[Bawnorton]

1.20rc-1 was released; 1.20 will have the same loot tables and recipes.

Changes:

• Added the 1.20 Loot-Tables
• Added 1.20 Panorama to Loot-Table Randomiser
• Updated Random Assistant meta (No longer in-dev)

Notes:

• I couldn't re-zip the data folders for some reason, every time I did the worker threw a JSON parse exception ¯\_(ツ)_/¯ and I'm not familiar enough with angular to diagnose why.

To Add:

• Crafting recipes for 1.20
• 1.20 Panorama to Crafting-Recipe Randomiser

Thanks! Once i've re-integrated the dev branch into the trunk, maintaining version should become a lot easier.
