Programmer Art Continuation Project - Base Pack r2.0_01

Bugfixes for 2.0. sory.

- Added 1.21 pottery sherds and patterns.
- Added 1.21 trims.
- Added 1.21 banner patterns. These were in my dev folder, I just forgot to add them to the zip. count this as a fix.
- Fixed bamboo sapling being used as the bamboo stalk.
- Fixed eyeblossom using the bedrock naming scheme. 
- (Hopefully) fixed bed items being broken on 1.21.4 - apparently "white bed" is just "bed" now.
